Loved the first one! Glad the first time I watched it it was subbed. It showed me what I'd been missing out on, with the subbed version of the show in general. The Moon Revenge sequence is probably one of my favorite moments of the series ever.
The second. I'm indifferent, to be honest. The whole subplot with Luna being in love with a human, I coulda done without. I also felt it lacked the epicness and character development that the first one had.
The third. A bit better, but like the actual season I felt it was too centred on Chibi Usa, who I honestly don't mind as a supporting character. Plus the outers just seemed to show up out of no where, with no explanation for why Pluto was back.
I guess I'm just not crazy about movies where the story doesn't focus on the title character. That's where the S and SuperS movies failed in my eyes.
