There was definitely some "hokey" acting in season 1&2, occasionally almost on the verge of self-parody. But at other times it was really good. A little choppy and inconsistent would probably be a better description?
But if you look back at shows like BSG or Firefly, they certainly weren't any better in terms of acting - I think we just have higher standards these days!
(By the way, if you didn't enjoy Season 1 (I did!), then you won't like Season 2 any better.)
