To quote Roger Ebert, I hated, hated, HATED this movie. For me, it was by far the worst of the three, and I didn’t care much for Reloaded either. It may even have sunk the trilogy - I may skip buying the eventual 3-movie box set which was previously an automatic purchase for me.
No-spoiler impressions: Interchangeable minor characters upstage major characters we know and love, thus making us care a lot less about their struggle. “Climactic” massive battle scene is very videogame-like, resulting in no emotional attachment to the characters, the stakes, or the outcome. Less pointless stoner pontificating than Reloaded, but not zero pointless stoner pontificating. Considered leaving several times when it beacme clear that the film couldn’t alienate me anymore than it had (I had to give a co-worker a ride home, so I couldn’t leave.)
The wire fu scenes are pretty.
