I also felt it took the multi-media thing too far by (I heard) having major plot points resolved offscreen. I did like several of the characters a lot, though.
Eh? Like what?
When I was watching it, it seemed necessary to follow all of the faux-websites. I'd also heard that the mystery of the numbers was revealed offscreen. Not sure of that, though, since as I said, it strung me along for too long.
As for B5's dialogue, I wonder what people would say about it if there wasn't so much exposition packed into so much of it. Lost and other shows do a 'previously on' segment at the top of the show to remind viewers of what went on before but for whatever reason, B5 only did that a few times.
