"I WANNA SEE THIS MOVIE!" my cousin told me... and I wasn't really all that surprised, it's pretty much the only kids movie out there. This was advertised to be in 3D before Avatar came out, it this wasn't the result of the now pending 3D craze we're going to see in the next 5+ years.
So far the most pleasent surprise of 2010. I went in expecting a "lulz I farted!" kids film, but instead got a well made movie that kept me interested till the end. Also, the 3D was well done. Like Avatar, it didn't constantly remind you that it was in 3D, thus making the effect more of an effect and less of a gimmick. The movie can be easily enjoyed in 2D, but for the record I wasn't dissapointed I bought a ticket for 3D.
As for the plot, it was predictable, but what could you expect? It's a film for kids, it uses plots that are familiar. The characters are memorable and believeable, and the voice acting is good (Kept smirking each time Stoick spoke, as I always expect him to yell "THIS IS SPARTA!" as he's voiced by Gerard Butler).
As a kids film, it gets a 9/10
As an actual film, it gets a 7.5/10 (I was expecting a 4/10)
