Pretty good, but a step down from the Original Series. In terms of negatives, the contest episodes mostly were pretty boring. A lot of them were all flash but with none of the intensity that usually makes the gym battle episodes so good. The battle centered ones were usually fine, however. Adding to this, the high amount of tournament arcs, as well as a lighter, more relaxed tone, resulted in there being less interesting episodes than the OS. But though it was weaker than the original, that doesn't mean it was BAD. There was still more good episodes than not, and quite a few (such asthe Swampert episode, Kyogre vs Groudon, or the one where Pikachu loses his memory, to name a few) that i'd definitely consider highlights of the overall show. The animation was still solid, and the humor was very good, with a lot of funny moments in most episodes. And when it came to emotion, it would consistently deliver.

Overall, weaker than the first series, but still enjoyable. If you liked the OS, you'll probably like this.
