The original Magnificent 7. I've been wanting to see this for a long time, and this desire had been kicked up a notch after seeing the remake (spits. Fuck that ending) in theaters last year. The original is kinda caught in the middle of the remake and the source material, Seven Samurai by Akira Kurosawa. As such, it really builds up to this big, chaotic battle at the end like the remake whereas Samurai was a war of attrition. Not as flashy as the remake, but it had the right heart and used the right ending (though not as beautifully handled as the source material's). Yul Brynner is fucking awesome and really felt like an American Kambei to me.
So: Seven Samurai (9/10) > Original Magnificent 7 (7.5/10) > Remake (5/10)
Maybe sometime I should get around to watching Samurai Seven. I remember that being on Razer all the time before it became MTV2, and from what I saw it was a pretty good anime.
