Robin Hood, hulk and batman have had countless adaptations and spin-offs. Total Recall was a one off so i don't see the comparison. The financial reason for the remake is probably Avatar which trudged into similar territory (albeit in a dull and predictable way).
Yes the superhero movies were just examples of hollywoods lack of respect.
However I can see Robin Hood is another type of film, a classic tale.
Would you say Predator is a better comparison? Or maybe Karate Kid?
Anyways, yes it could be good if they don't play on the Arnold movie at all and start fresh off the original short story.
Miami Vice btw was not a good remake imo.
