Perhaps nothing emphasizes how far superhero stories, with all their bizarre tropes and gimmicks, have permeated popular culture than this: in the past year, we have had not one, not two, not three, but four live action superhero mega-crossovers, each of them bringing together multiple superheroes from several different series for one big teamup.

That there are even enough live action superhero series going at once to make one such crossover possible is amazing. That there’s enough to do four, and that the people behind them are all willing to go through the logistical hoops needed to make such a crossover happen . . . as someone who remembers the state of superhero media in the 90’s, that’s a frickin’ miracle.

But, for all the hype surrounding these crossovers, how well do they actually hold up, and which ones do you feel worked best? Consider this an open forum to talk about anything at all related to Warner Bros.’ Justice League, Netflix’s The Defenders, The CW’s Crisis on Earth-X, and Marvel Studio’s Avengers: Infinity War.

Infinity War is still pretty new in theaters, though, so please, mark your spoilers, people.
