At first I hated them because of the way they were presented. I would have probably liked "Let's Go Rider Kick 2011" a little better if it wasn't the theme for the 40th Anniversary Movie.
Ever since I think avex / Toei are trying to shove them down our throats and I was one of the ones that was very vocal about them singing the main themes in Wizard.
However, ever since they started in Wizard their music became way better than what it was switching from basic Idol-ish stuff to more rock which culminated in Alteration which is one of the best toku albums of the year. Hell, they are even better than RIDER CHIPS this year IMHO!
Some songs are still TOO generic but songs like "Just the Beginning", "alteration" and "Missing Piece" are very awesome.

(UGH how do I stop the forums from auto-embedding videos? That's stupid)
That said, I was pretty indifferent about them at first, though I actually didn't mind their covers of the original's and V3's title themes, personally, but as of late, their Wizard tracks and stuff like Go Get 'em are just amazing.
