I just couldn’t get into the show. I watched the first 5 episodes and found it so dull. Maybe I’ll give it another chance.
I couldn't either... but my bride liked it, so I kept watching it with her. This was when we could snort the first 4 seasons rapidly. After a handful or so, I started to realize that it was really good show... provided I didn't let myself get affected by the lead actor, who was criminally miscast as the captain of a pirate space ship. I don't know who did the casting, but everybody else was exceedingly well cast, with the one great exception being the lead character. It made me wonder if this was some kind of joke, or maybe that guy put up all the money, or however else I could imagine the basis for that decision.
So my opinion is that it's very well worth it, provided that you can separate the show experience into two parts: (1) getting into the show without letting that one guy distract you with his inherent goofball presence, and (2) letting yourself laugh at the decision somebody made to have this bozo be the lead character when the rest of the cast is great.
