Two words: make more! I had a hard time deciding whether I like this or the first movie better. The first movie was less polished up (which is good and bad) yet random. Perhaps there is TOO much chemistry between the two of you, so some parts seems like they are made by the ssame person (joined up too well that it not random enough).
Well, that's just what I feel. Perhaps you two can find a third guy and try making another one. Things might turn up more jumbled up.
P.S. Including the "the world is destroyed" part in the first movie... the earth was blown up FOUR times. =P
