Great movie. For those who are doubtful, I'll try to say a few things without spoilers.
- They did an EXCELLENT job sticking to the classic LEGO style, unlike other LEGO movies. Everything in the LEGO world was made of LEGOs - explosions, lasers, etc, unless it just made no sense.
- Had some pretty original jokes in there. Plus, it was chock-ful of humor, all the way through.
- There was a unicorn kitty.
- TONS of great characters, including but not limited to Superman, Batman, Gandalf, Shaq, Dumbledore, and more.
- There were multiple plot twists.
- Morgan Freeman had a humorous character. Pure (voice) acting gold.
- The fight scenes are top notch.
- There's a freakin' good cop/bad cop - in one cop.
- Incredible attention to detail.
And last but not least, it had a quality plot. I thoroughly enjoyed it, and it is now my new favorite movie of all time, Annoying Orangeing WALL-E. Definitely watch it.
