My favorite is How to Train Your Dragon. No joke, that movie was great. Also, Toy Story 3. Yeah, they're kids' movies but they were both amazing. Honestly, I didn't like Inception all that much, people hyped it up way too much. I saw it and wasn't ever very interested, nor did I ever find it very confusing like many people said. I also don't get why people obsess over the ending. It's an ambiguous ending, there's evidence both ways. Personally, I don't find that all that great. Still a decent movie though.
Jackass 3D was also one of my favorites, haha.
