1. Yes. Especially if you are the fan of previous Part 1. It's not only unacceptable, it's illogical as well.
2. Not fake. The medias gave good reviews while most of the gamers gave bad reviews. Most of the medias gave reviews based on the gameplay itself. They skip the comment about story telling. On the other hand, gamers gave bad reviews solely due to the bad story telling. That's the reason why the media reviews are totally opposite to the gamer's reviews, by huge margin.
3. Not boring. However, it's disgusting. At some points, it may make you feel uncomfortable. Especially if you love the previous protagonist in Part 1.

Anyway, just continue your game journey. Till one point in the game, you will automatically know why people gave bad reviews on this game.
I haven't bought the game. Planned to buy it during future PSN sales. But after watching some game scenes myself (the game already released in US few days ago), I decided to skip this. It's not because of the bad reviews, it's because of me knowing that I won't enjoy this game at all due to the storyline, no matter how good the gameplay is. I don't hate the game, but I hate the way how they present the story.

However, if you don't care about the storyline at all, the gameplay and quality is the only things you are looking for, then this game is a must for you.
