I still stand by A Guide to Recognizing Your Saints as proof that he can act. He's the kind of actor that's as good as his director.
I agree. I really did enjoy this movie, didn't expect much, but it was a phenomenal character piece and the actors were all brilliant. Plus, his new film,
Foxcatcher, with a crazy, creepy-looking Steve Carell looks like it'll be an amazing film (I can already see Carell getting a Best Actor award for the role just from the short teaser they released).
I would love to see Venom again but in reality it is too early. We fans want to see him but from the general audience perspective Venom was in a movie not long ago. Also I think Spider-Man having the black suit first is the only good way to tell the story but it has been done already. It is too early to tell the same story and have the black suit on the movie posters again. I don't want to see the Ultimate version.
If we see Venom again he should look like this and the symbiote should feel more lively that it did in Spider-Man 3.
With the way these films have been going so far, dividing critics and audiences alike, I think that their best bet
is to revamp Venom.
Spider-Man 3 had the highest opening weekend record for the Spider-Man franchise for a reason, the reason being that Venom looked absolutely amazing in the marketing/advertising campaigns. The revamped Venom
will be Sony's saving grace for this Spidey franchise, just as it was the nail-in-the-coffin for the previous Raimi trilogy of films.
I might be alone here, but I don't like that choice. Once I see an actor in one superhero flick I can never look at them the same in a different one. Especially if the movie was recent.
The fact that he was wearing a mask the entire time in
The Dark Knight Rises further solidifies why he's the perfect candidate to be cast in a new Marvel movie. At least it isn't as crazy as casting Chris Evans as Human Torch and then Captain America, as if that worked out.

DC had a chance with him, and they killed him. Now let Marvel have their shot and I believe that a great film will be ahead of us. If I had to suggest a director for a solo Venom film, I'd say get the guy who directed Hardy in
Warrior, Gavin O'Connor, I think he'd make an amazing film.
