I'd say I'm off to a good start:
I'd reckon that I'm about halfway through the main game at this point. So far, this is the best LEGO game I've ever played (which includes Star Wars, Indiana Jones and Batman). The overlapping characters and worlds has led to some funny dialogue and situations. One of my favorite lines happens early on in the story when Batman ends up in Oz. But the Simpsons and the entire Portal level are hilarious as GLADOS has her typical snarky comments throughout and Homer is Homer. One level I wasn't sure about, the Midway level, was actually really fun to play. Having Wonder Woman and Stay Puft inside Gauntlet was awesome. And having never watched any of the new Dr. Who, I thought I'd be lost when playing that level, but that has also been one of the main highlights. Also, I love that Wyldstyle is animated differently than the rest of the characters. She has less FPS in her motions like the entire LEGO Movie was animated, very jumpy and erratic.
Now... if only they could get a few of these in the game next year:
