Coming into this i already knew how the endings going to be. But i was expecting something else that could maybe change the story to somewhat "better". But its exactly the same as the anime, but i don't know why the anime version is more amusing to me. The FL in this live action version, kinda annoys me especially when she's too caught up in her own "world".

The male characters are okay, i wish there was more time for us audience to get to know them a little bit better, because i caught my self only paying attention to one of the four ML.but visually they all looked really handsome though.

In conclusion i'd give this a 7.5.
If you're looking for something funny, and light you will like this, because regardless of a few "what the hell" moment, i still enjoy this movie.
