I have to say that I've not read the manga, so I had no idea what to expect before watching.

Though apparently some of those who read the manga would beg to differ, I actually don't think the story is the main issue. True, the way the movie depicts the struggle of a famous actor to accept his sexuality is simplistic at best, and for western audiences that might seem like a non-issue nowadays, but as Japan is a little more conservative when it comes to positive portrayals of LGBT, that wasn't much of a problem in my opinion.

What the movie actually lacks is good acting. I don't know whose fault is this - whether it's the director's or the actors' - but some scenes were so exaggerated and amateurishly acted that it made me physically cringe. Sometimes otherwise OK scenes (story-wise that is) were completely ruined by inappropriate facial expressions, vocal tones or gestures - For example, in one scene one of the actors, who was supposed to be terrified, visibly couldn't hold his laugh back.

The music also didn't help. Inconsistent and inappropriate at times.

Wouldn't watch again.
6/10, and I'm being generous.
