Speaking of ending themes, I really liked "Eternal Pose" with the collage of the SH through different arcs. Okay, the song is kinda like lame, generic Jpop/RnB, but still. The sequence was really nice, and the song went well with it.
Crazy Rainbow Star is cheesy and makes me cringe, but it's quite catchy in moderate amount. They should have just kept it for special occasions because, really, it's tiring after a while. Actually, come to think about it, all openings for OP are extremely cheesy, but at least they're not as long as CRS.
And I wish they'd give up the Roger intro and 5 mins recap. Fat chance, though :/
