So Help Me Todd (which I haven't watched) doesn't surprise me, and they really should have prepared for the possibility of being axed. The fact that they didn't, IMO, shows arrogance on the show's part. CSI:  Vegas shocks me, didn't think that would get axed. Oh man.

Casualties of the strikes. If they never happened, CSI: Vegas would've gotten a whole season and more of a chance to prove itself worthy of a season 4.

So Help Me Todd stink! But I'll miss CSI Vegas.

I've not watched either show, but I definitely figured they'd be Hollywood strike casualties.
