This is one of the most promising pilots of the season. The entire cast does very well in their interactions - that's why it works. One minor thing - the guy playing Casey seems like the weak link, acting-wise, but I hope he shapes up.
The jokes were all great, starting from meeting Casey, the sister rivalry, and jumping to the best part of the episode - the dinner. I especially loved Debra Jo Rupp - I guess it happens when you watch so much of "That '70s Show."
Joanna Garcia did well, just like in "Reba." I really hope the show continues doing great.
