I'm not sure I like that idea. I still hope animated features can get nominated for best picture even though they have their own category. Same with sci-fi/action/fantasy. I think when you categorize films like that it takes away any chance of best pic if it was ever to deserve it. Like Return of the King; it was nice to see a fantasy film taken seriously as a film despite a genre that often isn't. Like Brad Bird often states, animation isn't a genre like sci-fi fantasy, and if sci-fi fantasy/action whatever was it's own category, then I think it would equally hamper that particular sci-fi/whatever film's ability to be nominated for best pic even if it deserved it.
Animated films got their own category, which means, there's a reason to try to make a really good/great animated film, you can be rewarded for it. So tell Brad Bird to shut the f--- up...or give back his reward, saying that he wants a "Best Picture" one instead in protest!
Sci-Fi/Fantasy/Action should have theirs too, especially since they've been around a hell of lot longer than Animated films, bad, good and great. If you think about it, SM2 was one of most critically acclaimed films in 2004 (few if any live action films came close). Yet, The Incredible got their reward, but a film like SM2 had to settle for a Visual Effect award, which makes no damn sense. I'm telling you that they way it is now is pretty flaud. Hell, most of the films they choose for
Best Picture the majority don't agree with anyway.
Basically, what I'm saying is, if there was a category called best "sci-fi/fastasy/action" category, there would be a reason and a need to make much better action, sci-fi and fantasy films, because at the end of the day, or year should I say, you could be rewarded for it.
You wanna know who I think should present this idea to the Academy. Steven Spielberg, James Cameron, Ridley Scott, George Lucas and Peter Jackson. There's no reason why there should be an Animated category and not a S/F/A category.
