I thought the same thing. I felt like there was something I was missing considering I haven't played RE5 and the RE series really isn't even the same genre of game that enjoyed from 1-3. I didn't even bother finishing it, but I thought it was just me.
But from everything I've been reading about the full game, it's just amateur hour from beginning to end. I'd rent it and play it with a friend for a fun 'bad game night', but I already played Castlevania Lord of Shadow back in February.
Oh well, back to Dishonored.
