Yeah the first season is brilliant, second season seems to get a bit carried away with itself and a bit lost. But the characters are brilliant, we can't decide who we like more; Ed, Hawk, Cooper, Leland etc every character has a propose and a strong personality.
The music is also brilliant and it's a shame that season 2 drew away from it compared to season one, but the intro music is perfect.
I also have to say that it's really well shot too, watching it now if you didn't recognise the actors and actresses you'd struggle to know if it was an actual late 80's TV show or a modern TV show made to look old.
