^ That's a pretty accurate summation of the series, though I'd probably peg it slightly higher than just "average." startrekwatcher
is right, though, the series is at its absolute best when it focuses on its mythology. Where I disagree is with respect to the characters. It's not like they get a whole lot of development, but I find Olivia, Peter, and especially Walter to be very entertaining.
Best thing to do would be to rent S1 on Netflix. It does improve in the second half and, from there, you can decide whether or not its your cup of tea.
