I think that the Pixar movie "A Bugs Life" was one of the first movies I saw that featured a 'blooper reel' with outtakes and mistakes made by the animated characters during the making of the film.  The Toy Story franchise also does a great job of making you want to stick around for a blooper reel during the credits.

the Lego Movie has a blooper reel of its own.  Let's see how it stacks up.

Do you think it's just as good as Toy Story or Bugs Life?

I think the Lego Movie was AWESOME... but it's blooper reel lacks the charm of the others.  Which do you think is the best?
