Considering the quality of the show though, I have it to diminish over the years and greatly. I use to watch the show every chance I had, but in the past 7 years or so, I don't even bother to check out more than 1 episodes a season. Hell, I don't even know if it is still ongoing for that matter.
Point is, if the movie is practically just a longer episode, than I don't expect much from it. Personally I think they are trying to drag out old boring jokes and fill time. The spider pig part seemed unbarably long and stupid in the theatres during previews, and I expect a lot of the humour will be based off crappy scenes such as that. Without the cameos and sattire that should be exected from such a title, more uneducated aspects will be applied. Stupids jokes for the diminishing audience I guess..that is what I see from the poor ratings and actualy from the previws months ago.
