I always tell people that the series rewards patience and close attention. If you simply accept some of the SF aspects like hyperspace and PPGs as just being methods of transport and another form of gun, you'll find that the majority of the show is very character driven. The characters will grow and change and there's no 'reset button' to B5.
You're welcome to post here with youre impressions and questions, though. We enjoy that and we'll try to avoid spoilers when we answer.
