What do you think about black spider man in Spider-man ??

Erm, I'm guessing you're not familiar with Marvel characters and the actual Spiderman storyline. The black spiderman you're speaking of is Venom. He's an actual character in the Marvel characters, and an important character in the Spiderman storylines stemming from the comics. I for one am happy that Marvel is trying to go back to the comic base, since that's the origin of the story to begin with.

Well its different to watch in spider man

I wasnt dissapointed because black spiderman wasnt my main concern I know the black suit would come out great it was just portraying venom in the film that got me worried.At the end hollywood failed me by puttin venom in only for about 5 min of screentime (such as a dissapointment).
