The Hollywood Reporter favorably reviews "Megamind":
"Megamind" an early holiday-season 3D winner
... 'Megamind' is snappy good fun. ...
And gives high marks to this:
... [T]he film stands as one of the best arguments in favor of 3D among the many examples that have surfaced over the past couple of years in that it feels like mature, restrained, even natural use of the technique. ...
We think that DreamWorks Animation has just about the best 3-D going. So if you like 3-D, the films of DreamWorks Animation are the ones you need to see. Because the 3-D really works.
