Yeah, I heard it's enjoyable but not spectacular, and there's some question as to whether that'll be enough to hold an audience.
Slate just blasted it, though, for not being the answer to the modern anti-hero.
Well, the cast has a lot to carry in a largely pedestrian comic book TV show. If Firefly had featured a bland cast with no real chemistry together, it would not be remembered as fondly as it is today. Same with Buffy, which was actually a pretty mediocre show otherwise much of the time. And don't even get me started on Angel, which was practically unwatchable but rode Buffy's coattails for a few seasons.
Looking at who they are, I don't know if I get the feel of a Buffy or Firefly-level of smart casting.
I don't think overall this will be one of the better seasons for new TV debuts, and especially not on the networks.
