Well, people, you get what you asked for...
You wanted a sequel, and wouldn't stop saying it. Making sequels to movies is boring and annoying, especially trying to make one that does justice to the current Top Three Banana Phone. People wouldn't stop bugging him, so this is his version of a middle finger to your faces. I wouldn't want to try to top it either...so stop asking for another sequel, because this guy made it as a one-movie series, it was NOT meant to be continued.
