I didn't watch the Brothers Garcia, but I did watch Complete Savages and Oliver Beene enough to love the shows (but not as much as MitM). God rest their souls....
I really liked complete savages too, but sadly it only lasted 1/2 a season then got canned. I think it was better than most of the sitcoms they kept. I guess it's just a matter of opinion (and money) though.
I've been getting into The War at Home a bit this season. I mainly started watching because Kyle Sullivan, who played Dabney on MITM, starred. It's similar in some ways, but the comedy is much more stand-up and direct, rather than the subtle humor MITM fans have become accostomed to. (Sometimes it's good to not hav eto think in order to understand the joke. )
