I'm a pretty big fan of Keanu Reeves and I think he receives a LOT of unjustified flack from movie buffs.
However, I cannot believed The Replacements have made two people's lists thus far. I'm like, literally shocked. Street Kings, too? These are easily two of Keanu's worst films. I really dug The Replacements when I was a teenager, but seeing it again I guess about a year or so ago, the movie sucks outside of a couple of one liners from the underrated Orlando Jones. And Street Kings is just dumb, annoying shit. I HATED it.
Now, here are the list of good films starring Keanu and those which contain his best performances:
River's Edge
Dangerous Liaisons
Bill & Ted's Excellent Adventure
I Love You to Death
Point Break
My Own Private Idaho
Speed
The Matrix
The Devil's Advocate
All these films crush The Replacements and Street Kings. Hell, his mediocre flicks like The Night Before, Bram Stoker's Dracula, Little Budda, Johnny Mnemonic, Feeling Minnesota, The Gift, Something's Gotta Give, Constantine, and even sappy over-dramatics like The Lake House and Hardball are better than The Replacements and Street Kings.
Haha... sorry to get on your case a bit, guys; I know it just your opinion, but man I'm truly baffled by the selections, lol.
Anyways, Keanu's best performance is undoubtedly in Dangerous Liaisons, which is an overlooked classic. However, it's not my favorite film from him. My favorite comes between perhaps his three most popular movies to date: Point Break, Speed, and The Matrix. I love all three films, and fuck it's REALLY hard to decide, but man... I have to go with Point Break, simply because I saw it when it was first released on video tape when I was a kid, and have never grown tired of it, no matter how many times I've sat through the film all the way through. Not to say I've ever grown tired of The Matrix and Speed, but Point Break barely gets the edge since I saw it well before I ever saw Speed and The Matrix.
