So, general thoughts:
-Interstellar: I'll be honest, there's something about this movie that puts me off it. I think it's due to the premise that "mankind screws up the Earth" (though by the trailers, "screwing up" only means duststorms and crop fires), travels using FTL technology (apparently the rest of the world didn't advance as well), to find a new planet where no doubt humanity will stuff things up as well." Um, yay?
I guess what bugs me at the end of the day is that the whole "end of the Earth" thing feels forced to me. I'd have been happy to have a story about space exploration in of itself, but the apocalypse angle reeks of forced drama.
-Big Hero 6: Eh. It's a Marvel movie, so that's a mark down in my book (ducks flying object). This is very much a taste thing, but I liked the film far more when it was showing Hiro and Baymax, the idea of themes of growing up, friendship, etc., instead of what now appears as a run-of-the-mill superhero movie. Yeah, given the source material I suppose a superhero movie is what people want, but not really my thing.
-Mockingjay: Cautiously optimistic. Mockingjay is the best book in the trilogy IMO, and the second film was a distinct improvement over the first one. Given the nature of the book, I think there's a logical mid-point (no, I won't spoil it), so I could see the split format working.
-The Battle of the Five Armies: I'm not expecting much from this. While I consider 'The Desolation of Smaug' to be a good movie in of itself, I don't consider it to be a good adaptation. 'An Unexpected Journey' had problems, but it was offset by having a spirit that felt distinct from 'Lord of the Rings' and feeling true to the novel. The third film however, I'm expecting the worst of both worlds. Padding, padding, and more padding for a battle that I'm sure will be epic, but with style over substance.
