I liked the movie...and from the begining i had no impression he was alive...since they kept to the story of him drowning.....there was no info about him surviving(just that he came back)...so from the get go...i dont think he was just alive and a normal maniac......i gotta say he was one hell of a marksman.....the end could be a dream sequence.....but i don think they will get the same actors in this day and age...so i think if there is a sequel....it wont be a dream sequence
