I thought that Despicable me 2 was a pretty good movie with one real flaw.  That flaw is that the
movie hurts itself by using the traditional one hour and thirty minute handicap that most animated
movies put upon themselves. 

How this problem effected Despicable me 2 in a negative way was that the movie decided to pace
itself, slowly building up the relationship between Gru and Lucy while also slowly hinting at what
the villain was up to, and then it realized it had to speed up the ending to stay within the hour
and a half limit. 

So once Gru discovered that El Macho was indeed still alive, it was time to speed up the movie to
keep within the allotted time, making the last act of the movie the least enjoyable.  There was so
much missed opportunity in this ending.  They really needed to pace themselves in order to properly
utilize  elements like El Macho’s son (who was zapped by the freeze ray and then never seen again)
who could have been the evil mastermind behind the whole thing (proving Gru right), Dr. Nefario who
betrayed Gru by helping El Macho and how he needed a little bit of a chance at redemption (But they
threw away that opportunity far too quickly by having Dr. Nefario instantly turn good again the moment
Gru found out about El Macho’s plan), and at least give the purple mutant minions more screen time
(in fact, the regular minions needed more screen time too).    

If I took time to think about this more, I’m sure I would think of more things I thought they missed out
on, but honestly, if they had paced the ending better, I probably would think that Despicable me 2 was
a perfect sequel for the franchise.
