10 Comic Book Supervillains Who ACTUALLY Deserve A Solo Movie
9. Sinestro
Sinestro is another one of those characters whose on-screen appearances (or in this case one appearance) hasn't exactly been the most celebrated, despite Mark Strong's performance probably being the best thing about the 2011 Green Lantern (which, admittedly, isn't much of a feat).
Anyhow, though the Yellow Lantern's history is generally overlooked in favour of him merely fulfilling his role as Hal Jordan's mentor gone bad, this is rather offensive to how great the character's tale actually is, with Sinestro being an explorer prior to his days as a Lantern making his backstory one of the more interesting on this list.
Giving the character a movie containing a fleshed-out backstory would go a long way to humanize one of the most prominent features of the lantern mythos and help make his appearance in future films a lot more meaningful.
