There's only one that really gets on my nerves:
1. Slumdog Millionaire: This movie was horrible. How it even got a nod from the Academy is beyond me, but everything about this movie: the plot, the format, the acting, was just mediocre and sub-par. Not to mention it was really boring, and most Best Picture Winners I can stay awake to, but not this one.
Runner-up:
Inception: Now, before you yell at me, I have seen the movie three times fully through. The first time I watched it with friends, and I left (my friends' house), thinking, "What on earth was that?" I was utterly confused, and I didn't like it at all. The next time I watched it on HBO, and I loved it. I understood it more, and the story made sense this time. Not to mention the acting really stood out, and people like Ellen Page did a great job. Then I watched it another time, again on television, and it really became, for me, at least, one of my favorite movies of all time. I realize how emotional the movie is, and I got deep into the side plot with Cobb and his wife, and I almost cried at the ending. Inception's really one of those movies you have to see more than once to enjoy, and I'm glad that I did.
