Totally agree with both of these. One that always comes to my mind is I Am Legend. Movie would be incredible if they used actors for the monsters. I'm not scared of CGI haha
I was going to say I Am Legend, but I still enjoyed the movie a lot.
I really did enjoy the movie too. I think it would be in my top 10 though if it was just a bit more grounded in reality to the point where we could say, "oh shit, this could happen."
