I enjoyed the first and second installments. The third, I wasn't too crazy about, and the other two I don't even remember all that well.

Will I watch it? Eventually. But I feel, that in a way, they are butchering a good thing, with way too many sequels. Originally, it was a unique concept, and something most people weren't used to watching. But now, it has become the norm, and there isn't anything special about the sequels.
