I've only joined this community like 2 months ago so I didn't experience as much of the characters as you people did, but I'll answer anyway.
I didn't like Rin at first. Now she is one of my favourites. I think the main reason is me being exposed to more LL songs and liking Iida Riho's voice.
Other than that my opinion on the idols didn't really change since my initial impressions.
Also, I agree with firehawk12.
