Rescue Me: Has This Season Saved the Show?

There's something different about Rescue Me this season that we can't quite put a finger on.

Maybe it's the complete creative rejuvenation of the show after a long, 18-month hiatus. Maybe it's the addition of the shockingly grotesque, wheelchair-bound Dwight, played brilliantly against type by guest star Michael J. Fox. Maybe it's that the show returned its focus to 9/11 and its lasting effects on the firefighters. Or maybe it's just because Season 4's look at a sober Tommy Gavin was a bit of a stinker.
