Here's my predictions who will win oscars, along with who I want rather to win, and all the major snubs that I felt happened when nominees were announced.

Refer to Nominations list here - http://oscar.go.com/nominees

And the Oscar goes to 

Best Picture 


Will Win/Should Win : La La Land
Snub : Paterson

Its between La La Land and Moonlight. Would be surprised if Manchester by Sea or Hidden Figures win. Paterson deserved a nomination here instead of Fences. 


Actor in a Leading Role 

Will Win/Should Win : Casey Affleck (Manchester by Sea)
Snub : Adam Driver (Paterson)

Denzel Washington (Fences) at the moment only one who could take oscar away from Casey. Personally, I loved Casey performance lot more plus the movie is as good too. While Denzel performance is solid, but can't say same about the movie specially that 3rd act which falls flat for me. Ryan (La La Land) would be a pleasant surprise but don't see it happening. And Adam Driver was fantastic in Paterson, totally deserved a nomination.


Actress in a Leading Role 

Will Win : Isabelle Huppert (Elle)
Should Win : Emma Stone (La La Land) 
Snub : Amy Adams (Arrival)

This is easily the most competitive category this year. Performance wise, Isabelle is well ahead of all here, but I badly want Emma Stone to win, consider it as baised opinion. Natalie (Jackie) has a good chance too but feel she will miss out. Oh, but how did Amy Adams not make it to the nominee list, seriously? And, Voila Davis should be in this category, not Supporting! 


Actor in a Supporting Role 

Will Win : Mahershala Ali (Moonlight)
Should Win : Dev Patel (Lion)

Mahershala Ali would definately win here, and I had loved his performance too. Want Dev Patel to win, only because as Indian that would be a great moment if it happens. Jeff Bridges (Hell or High Water) only other nominee who has outside chance to win. 


Actress in a Supporting Role 

Will Win/Should Win : Viola Davis (Fences)
Snub : Janelle Monae (Hidden Figures)

This is also straightforward, Viola to win with only Naomie Harris (Moonlight) posing some threat. And I prefer Janelle over Octavia Spencer (Hidden Figures). 


Animated Feature Film 

Will Win/Should Win : Zootopia 

Haven't seen Red Turtle and Zucchini. Moana was good, but no chance of getting oscar at all. Kubo I personally liked a lot but its no where close to how good Zootopia was. 


Cinematography

Will Win/Should Win : Linus Sandgren (La La Land)

Both Moonlight and Silence are strong contenders, but feel La La Land should sneek in with a win here. 


Costume Design 

Will Win/Should Win : Mary Zophres (La La Land) 

Haven't seen Allied and Florence Foster Jenkins. Out of remaining three, La La Land looks deserving to win, with Fantastic Beasts having slight possibility. 


Directing

Will Win/Should Win : Damien Chazelle (La La Land)
Snub : Jim Jarmusch (Paterson)

Damien should win this one, though you never know if Barry Jenkins (Moonlight) pulls off a surprise win, would be harsh calling it upset. Mel Gibson (Hacksaw Ridge) did incredibly well in the war scenes but in comparison Jim direction was pitch perfect throughout in Paterson that didn't get a nomination.


Film Editing

Will Win : Tom Cross (La La Land)
Should Win : Joe Walker (Arrival)
Snub : Sebastian Sepulveda (Jackie)

Most likely Tom Cross will win it, unless they give to Gilbert (Hacksaw Ridge). Personally I would have Sebastian nominated instead of Gilbert as there were only 2 things that I liked a lot in Jackie, one being Natalie's performance and other editing. I would prefer Walker win it, but it won't happen.


Music (Original Score)

Will Win/Should Win : Justin Hurwitz (La La Land)

This is one award that no one else has no right in winning, just give it to Justin, else I am gonna be super angry. I understand Oscars have got some kind of rules where you can't have pre-existing music in films, still scores of Arrival and Manchester by Sea were too good for me. And I don't get it for what Jackie got nominated here, its score kept putting me off from the narrative.


Music (Original Song)

 Will Win : Audition (The Fools Who Dream), Justin Hurwitz, Benj Pasek, Justin Paul (La La Land)
Should Win : City of Stars, Justin Hurwitz, Benj Pasek, Justin Paul (La La Land)

I love lyrics of Audition, but really prefer City of Stars. That whistle and the pleasant feel song has, can listen to it non-stop. Moana's 'How Far I will go' could play spoilsport here but I feel La La Land will win, just the question is for which song.


Production Design

Will Win/Should Win : David Wasco, Sandy Reynolds Wasco (La La Land)

La La Land favourite, but feel Hail Caesar has a great chance here just incase Oscar ppl want to give other films some awards too. I won't mind Arrival winning either, those spaceship sequences were really well done.


Sound Editing 

Will Win : Robert Mackenzie and Andy Wright (Hacksaw Ridge)
Should Win : Sylvain Bellemare (Arrival) 

Hacksaw Ridge most likely will win here, La La Land has a outside chance too but I would be more happy if Sylvain wins it for Arrival. Best result would be Hacksaw Ridge winning Sound Mixing and Arrival Sound Editing.


Sound Mixing 

Will Win/Should Win : Kevin O Connell, Andy Wright, Robert Mackenzie and Peter Grace (Hacksaw Ridge)


Visual Effects 

Will Win/Should Win : Robert Legato, Adam Valdez, Andrew R Jones and Dan Lemmon (The Jungle Book) 

 Even though I liked visual effects of Doctor Strange a lot, the oscar has to go to Jungle Book only.


Writing (Adapted Screenplay)

Will Win : Barry Jenkins and Tarell Alvin McCraney (Moonlight) 
Should Win : Eric Heisserer (Arrival)

 Slightly confused here, want Eric to win for Arrival, but won't be unhappy if Moonlight wins too which in most likelyhood it will.


Writing (Original Screenplay)

 Will/Should Win : Damien Chazelle (La La Land)

 La La Land is a clear winner here, would be a surprise if Hell or High Water/Manchester by Sea pull off an upset.


Haven't predicted for 6 categories, as not seen majority of movies nominated in them.
