That's so similar to me!
I watched the first one at a friends house, and we were watching it in dribs and drabs and I got bored.... Found it a bit confusing and havn't watched it since.
I have no intention at the moment of going and seeing the second one because a) Its a carry on plot from the first and b) 3 Hours of BB > 3 hours of Matrix

Like you, I think they are films I would really like - I just need to get around to watching them!
I think there is a third Matrix coming out in a month... So after that I imagine they will release all three on DVD in a set..... Then I might be tempted to go and buy and have a quiet evening in lol
If you want to see a confusing film, try Donnie Darko - I had to watch that film about 5 times and still now I don't get it all
