I wonder whether Buffy holds up (the first season doesn't for sure).
Buffy s1 sucks, s2 isn't too bad, s3 is good.
Firefly is a lot of of fun, naysayers are TheBusiness-level killjoys. As it turns out,
Serenity, the Firefly movie, is also a killjoy.
People say
Angel is really good, but I don't like Borneas enough to look into it, despite Charisma Carpenter appearing regularly.
Dollhouse starts off very weak, and quite uncomfortably. It's creepy. Then it gets quite interesting.
