These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Love Live
Alternate Character Interpretation: Eli, did she upload the groups first concert to the net because she wanted them to be seen as foolish, or did she really believe that the group was good and could save the school.
Broken Base: Over the anime's penultimate episode. Opinions are heavily split about Honoka's reactions to what happened in said episode, whether or not the actions taken by the rest of the group were justified, and some complained about how much more drama the episode had compared to most of the others.
Ensemble Darkhorse: Maki is very popular, with a winning combination of being a Redheaded tsundere who's more dere than tsun. Before the anime aired she was fairly popular, but the anime really skyrocketed her popularity. Because of this, she won the poll to determine who'll be the center of their 6th PV, beating out the group leader Honoka and the other breakout character Eri.
Family-Unfriendly Aesop: Be selfish and you'll get anything you want if you're charismatic enough about it. The final episode of the anime pretty much states this outright.
I Am Not Shazam: Some viewers actually thought the group was called Love Livenote The name of the idol competition. They are actually called μ's, pronounced muse.
Tear Jerker: Episode 3; After spending countless hours training for their first concert, even spending half the episode passing out flyers for the event, Honoka, Umi, and Kotori are greeted to an empty auditorium room. Even Honoka is in tears, feeling that all their efforts were wasted. Luckily, it turned out alright.
Episodes 12 and the first part of 13 are littered with them. The drama in both of these episodes is rather high, and is in stark contrast to the earlier episodes where the mood was relatively cheerful and upbeat.
