Hello,
It will be my first review so please be gentle :) I am sorry if I'll make any mistake coz I'm not native English speaker.
So firstly, I have to write that this is uncommon anime type. It made me laugh a lot, but sometimes I had to press pause button and think for a while... Characters are great! With each episode I started to falling in love with them more and more. The main plot is superb, I felt that everything is planned well and action is spreaded very nicely. Music is enjoyable, first opening was the best for me. Art is nice too.
Overally, I enjoyed this anime very much, and I would recommend this show to everyone who's not scared of thinking while watching, coz in my opinion, Mawaru Penguindrum is kind of deep animation.
BTW. Penguins are the best !
