Do yourself a favour and watch this movie... I watched it without my kids 'cause they're far too old for it now. I almost overlooked it thinking it would just be a cheap Pixar knock-off, but now I'm glad I didn't. The animation is solid, the voice acting near flawless, and the story/ character development on-point... You almost forget it's a bunch of goofy little green guys trying to punch above their weight class.
Ok it's not as good as original Shrek, but on-par if not better than the sequels, and I found my self chuckling out-loud at points, and almost tearing up at others... Good stuff... Sniff.
Hell, you might even want to let your kids watch it with ya...
