First season of Avatar is hit or miss. Doesn't help that it has the undisputed worst episode of the series (The Great Divide, though honestly if that's your worst episode, you're in solid shape). Gets better towards the end though, and Season 2 is pretty top notch. Season 3 is also a bit hit or miss, depending on how you feel about the importance of some of the supposed filler in it. But the animation of each season upgrades a ton as it goes, to the point that it's hard to even recognize the series almost at the end, and especially at The Legend of Korra.
Never played Professor Layton...never was a fan of puzzles short of the logic puzzles I used to get at school.
Also, another YJ note...hurray for Wally keeping Artemis on lock for 5 years.
