I've watched this series multiple times and it is always entertainig. The characters are compelling and expirience consistent growth, the music is really good (although, I admit it took me more than one listen to start feeling it), the live/prims show secuences are pretty well done and hold up fairly good, the story has a little bit of everything: drama, romance, inter-dimensional shennanigans, humor. ***SPOILER*** My only complain is espisode 51. It was... underwelming, like, episode 50 was the absolute climax, the best of the best and then 51 just... is... such a drastic tone change. but anyway, the rest of the series is excelent and the bestpart is that you can watch this without having watched the previous ones, at least in my opinion, mainly because this is an entierly new group of characters, and every dinamic and relevant piece of lore for this show is explained on the first couple episodes, so, the most you'll be missing out for not knowing about the previous seasons are some background cameos and references.
