What irks me about the anime is the lack of a rival for the big show.
There was always A-Rise as the big obstacle to overcome, and then they do it in the prelims, and it isn't even really shown, just a bit in a flashback of the next episode. And then there is the Love Live, the big goal the have worked to, without any actual rival, there is no sense of danger of being defeated at all.
And in general with Love Live: Since almost all the songs are always sung by all 9, they lack character, they all sound the same. They are good and there isn't any i really dislike (like i dislike some of the im@s songs), but there isn't any really standing out (like some of the im@s songs which just blew me away when i first heard them).
