I think, given what they're capable of, I'd rather them take on something with a grander spectacle in the sense that a solo film, about a singular character just isn't going to cut it. I wouldn't want them behind a Batman or Superman film for example. If a script could get written to include several Green Lanterns, or even the Corps as a whole, then I'd love for them to take that on. Failing that, Flashpoint, but only in the sense that it wouldn't be specifically a story about Barry Allen, it would be a larger story of which Barry Allen would play a large part of. I was tempted to say a sequel to Justice League too, but I think they'd be best to leave that alone for a while until they can decide what to do about their Batman and Superman casting situations.
