It's very unlikely that route C will salvage your opinion of the game. This is why I'm bitter about noisily-held opinions of this game: others say they aren't enjoying the game and it really isn't that good? You just haven't given it a chance! Play through route C and all will be redeemed!

It won't.

You even saw it up above with that one person who said that, even though I had played through all routes and didn't enjoy it, must have "written it off and not given it a chance as you played it". As though I don't care for my time.
