Good, but must Gillian, Rigby, and Zack carry the whole show?

It's a good show but I suspect that the show's survival relies way too heavily on Britt Irvin, Meghan Rath, and Zak Santiago to carry it. Don't get me wrong, the other actors are good, but the show would face disaster if any of the three I mentioned were to depart. And let's face it, folks, these three will all be moving on to bigger and better things someday, especially Ms. Irvin.

Anybody who follows Irvin knows she is being cast to play bigger and better roles these days, and it's no secret that she's trying to cross over from TV roles to film roles. Given current trends, she will probably complete the crossover within two to three years. Her fan base might stick around as long as she leaves on good terms, IF the show gets to a point where it would be good even if she wasn't in it, and if she leaves the show on good terms.
