The "plot holes" you're calling out actually are explained in the game.
It sounds like you didn't even pay attention.
Also, platinumed in 6 hours ? Really ? I finished it in 11h in Hard Mode, and didn't even get the Platinum. But oh well, you're probably just insanely good at this game.
But I must admit I agree with one thing, fighting the Lycans was absolutely boring. A true shame.
Just because you have an opinion doesn't mean you are necessarily right.
