The fight scene is really impressive.  I love how stuff was broken when they fought.  Audio levels need a bit of work I think, though.  It's a bit hard to hear the voices at times.

The pacing was a little slow, but overall it was very good. I'm not sure whether I'm meant to take the superhero with a big shark head seriously.

Here's a tip for making your films look more believable and less like someone moving around LEGO people: bring the camera down to the same level as the figures. Live-action movies aren't shot from above, so when you're looking down on the minifigs it weakens the illusion a little.
