Well today I have just finished watching season 5 (In a row from 1) and I have to say it was the best season so far. And I have started on season 6, cant wait to meet Minin(?)!
The episode I liked the most was the one where they go into Larvitar's mind, that was awesome and the episodes plot was like a watching a good drama show. I felt like weeping a little bit when I saw how hard Larvitar was trying to break free of the "prison" and trust humans.
