1990: Back To The Future III (I have not seen a lot of the apparently great movies from 1990)
1991: Terminator 2 (oh my GOD yes)
1992: Toss-up between Reservoir Dogs and My Cousin Vinny (what? Don't look at me like that.)
1993: Groundhog Day
1994: Leon The Professional... is what I would say if Street Fighter hadn't come out that year.
1995: Toy Story
1996: Space Jam even though it's not a very good film.
1997: Princess Mononoke
1998: Following
1999: Star Wars Episode 1 has brought me a lot of amusement but it's mostly been mocking the film, so I'll say The Matrix instead.
2000: Memento
2001: Pretty decent year but I'm going with the majority on this and saying LotR: Fellowship
2002: Star Wars episode II was too bad to even mock for fun. LotR: Two Towers
2003: It'd be Kill Bill if it weren't LotR: Return of the King
2004: The Incredibles
2005: Serenity
2006: Pan's Labyrinth
2007: Sunshine
2008: Am I going to be the one who says The Dark Knight? Is that too obvious? It was good.
2009: Up
2010: BWOOOOOOOOOOOOOOOONG (Inception)
2011: The Cabin In The Woods
2012: The Avengers Some years were hard because I liked a lot of them. Some were hard because I didn't see many from it. I chose a lot based on how much pleasure they brought me, either from the film itself or from joking about it with friends or online, not how good the films were.
