I get that folks like the Tower of Babel story. I like it, as well. But it works in the context of a well developed Justice League that people know about and that exists for the purpose of essentially doing what the Avengers (movie and comic versions) are doing IMO--banding together to take on a larger threat. Not somehow twisted into the premise for the first ever Justice League film.
The comparisons between JLA and Avengers would be inevitable, but unavoidable. If Superman could deal with threats on his own, then there would be no reason for the team to exist.
