Thank God Your Here itself is a cool, inventive idea. Gather a group of C List actors and comedians and force them into situations requiring them to think on their feet while performing an improv skit. The only problem is that the entertainment of the show solely relies on the actor's ability to improv. In some cases the performer has been able to think on their feet and create a really entertaining scene (like Shannon Elizabeth, Chelsea Handler, Bryan Cranston, Fran Drescher) however there have also been the performer's that aren't very good at thinking on their feet and just sort of go with the flow instead of taking control of the scene and guiding it to funnier places (Tom Green, Tom Arnold, Joel McHale). I would definitely recommend you take a look at the show and decide for yourself, it's a show that can be really funny at times.
