2. Elektra
As much as female superhero movies are in short supply, Elektra isn't one of those who is big enough to carry the torch for the ladies. She's a potentially great supporting character but, in this case, they've tried once and failed and the idea of Elektra as a titular Hollywood star should be put to bed. The Jennifer Garner movie was a spin-off of an already poor Daredevil movie, so it was pretty much doomed to fail from the start but, even if that hadn't been the case, the character simply isn't strong enough and doesn't have enough of a fan-base for a self-titled movie. Terence Stamp - comic book movie legend and all round great actor - couldn't save the last attempt at an Elektra movie, so the signs aren't good for an Elektra movie ever working. Leave it well alone.
