The thought of AT ending makes me sad no matter what, but I think a movie could be pretty great as an ending. The movie will have to be really good tho. I mean it has to have a good story and have a lot if of feeling in it. Not like just another "kids movie", if you get what I mean?
I would get upset if it was the finale AT is such a good show and it be so disappointing is it were to end soon, i think the movie will trigger something for future episodes, or there will be a bunch of episodes that lead up to the movie. also when is the movie released?
