The start of BSG is so good. One of the best, if not the best, starts of any show. 33, in particular, is so strong. It really makes you feel the pressure that they're being hunted.

Sadly the end of the show isn't nearly as good. It's not a Game of Thrones ending, but it's a drop in quality from the start, but I don't know how you'd end it with the same level as it starts.
