A little disappointing after the huge wait between Season 4 and Part 1, but I guess it won't be an incredibly long wait. And I at least have a lot to do in the meantime.
Currently Season 4, but Season 5 seems to be on the brink of overtaking it - if Part 2 is as good as Part 1. Season 4 has some of my favorite episodes and moments and had a great story arc.
Who knows how the show would've gone had it never attracted a fandom? The fandom definitely had a role in making the show the success it was, or else it might've ended up being another forgotten "kiddy" cartoon.
Definitely a season highlight. Great Luna development and fun exploring the various dreams. I will agree the ending was too rushed but apart from that it was very good.
