Yeah, it's a noticeably different take from the comics, same with Eddie and his symbiote. But I found it enjoyable at least, and the dynamic between Cletus and Shriek was the most compelling part of the movie for me.
As for the bond between the symbiotes and their hosts. I'm mainly unused to seeing the symbiotes have such distinct personalities. In any other medium they're clearly seperate entities but move with such a unified sense of purpose that they more or less become on entity, which is where they get their greater power from.
In short, the movie makes a lot of changes from the comics, both big and small. But none of it was like frustrating or anything like that. Again, it's an enjoyable monster action movie.
