2) Blade
The first two Blade movies were pretty great, but everything went horribly wrong for the franchise when Blade: Trinity was released.
A complete and utter mess, the series was put on hold and the rights eventually ended up returning to Marvel Studios. Since then, he’s become yet another character left on the shelf, and while Wesley Snipes has teased some sort of involvement with a Blade 4, Marvel would be much better off starting from scratch by giving the vampire hunter a chance to shine on Netflix.
Bringing vampires into the Marvel Cinematic Universe would be a bold move, but one which could really shake things up in an exciting way, especially as this would be unlike anything we’ve seen in this world before now (plus, it could lead to Morbius’ introduction…).
