The third season may very well be my favorite so far. Not to imply that the other seasons aren't great. We left off last season with Vince getting ready to shoot Aquaman and now we're back after the movie has wrapped and is ready to premiere. This season has character development in spades and the cast are given equal screen time to shine (save for Debi Mazur who's pregnant this season). To go into detail would ruin the experience.
Another of my favorite aspects of this show are the amount of locations. This show shoots all over Hollywood and you get to see a lot of it in this season, from the Aquaman premiere in west LA, to the Warner and Universal lots, to a house party in Encino, this show is always on the move. We even catch a glimpse of Vince in the Aquaman movie at the Santa Monica pier. Best of all is when the boys hit Vegas and bump into Seth Green and his entourage. By far my favorite cameo. Other notables are James Woods, Paul Haggis and Ed Burns.
Overall, a very entertaining show with a continually developing storyline. It's very funny, with plenty of industry inside jokes, but it's also got some great drama(and I don't mean Johnny, but he's good too.) Despite it being Part 1, it's got an excellent cliffhanger ending to reel you in for more. I caught the new episode tonight and it's hard to wait week to week instead of one after another on dvd, the way this show is meant to be watched, like one long movie. Can't get enough of this show.
