I don't know how anyone can call themselves a "fan" if they generally pan the second season, as the second season is, in fact, about 75% of the series.
Nah, well I'm sure that most people dislike only the parts from Ep.17 on... (after Leland's death for those who have numeration problems ;-)).
That's why I always found the term "Season 2" very misguiding. Technically Eps. 8-29 are season 2 but in fact these are two different parts of the series: Eps. 8-16, being perhaps THE BEST part of the series (my favourite epiosdes definitely are there, even if Season 1 was more artistically consistent and succesful as a whole) - and Eps. 17-28, being quite obviously the worst part of the series.
Yet... I still like it very much, so:
I think that it's generally under rated!
In some ways if the show was gonna end after Ep29 I would have rathered that it just ended after Ep16 (and a bit of tying up loose ends as well of course)
