Season 5 is good. It has its weak points (like byron), but its still a good season. I had some rather severe problems with certain things
but overall it was a good season of a great show. It doesn't have any spectacularly bad episodes from what I remember (although considering the fact that Season 4 ended with the worst episode of a Sci Fi show that I've ever seen, The Deconstruction of Falling Stars
, its possible that it has some stinkers that just get over shadowed in my mind by that pile of garbage). The telepath arc is somewhat lame, but it doesn't ruin the season. If you liked the first 4 seasons, season 5 is a must watch.
