I watched AUJ and DOS, but not B5A. I recall that the first time I watched AUJ, in theatre, it made a good enough impression to make me invested in the movie. However, A few weeks later I tried watching it again with some friends on DVD, and we all got so bored that somewhere in Rivendell we've fully stopped paying attention to the movie and shortly after stopped it and switched to other forms of entertainment. Whatever value it had initially, it didn't hold on a repeat viewing. As for DOS, I didn't find it gripping even in the theatre. I have very little to say about the specific pros and cons, and don't want to party poop on the discussion, but I'm afraid my only contribution can be that the movies had neither enough emotion, nor philosophy, nor adventure to captivate me, despite all the attempts at deep moments and action scenes.
As for B5A, I enjoyed immensely reading everyone else's takes on that, and I believe at some point was joking about a new themed WW game, CGI: The Attack of the Wereworms. That's probably my fondest memory.
