The Elder Son wanted to watch the 2nd Matrix movie tonight, but since The Daughter had never seen the first one, we watched it again so she'd have a clue. It's been a year since we watched it last. There is a trailer embedded at that link.
There is a fan site here. The BBC reviewed it here. The BFI has a review here. Roger Ebert's review is here, Salon.com's here, The New York Times reviews it here and RollingStone here. HollywoodJesus draws out the Christian parallels. EW gave it a C+ and a condescending review.
DecentFilms calls it "the most influential action movie since Star Wars" and "a cleverly made movie, but not a profound one".
We didn't end up watching the sequel.
