I watched this recently. I thought it was good the first time but now there are some issues.
I did like the fact that it started out with Pachirisu getting stuck in Hippowdon but then things got messy. I didn't like how Hippopotas appeared all of a sudden. That made things a little crowded.
Then we get the usual Team Rocket and their rival Butch and Cassidy thrown into the mix. It seemed like too many event happening at once :S 4/10
