Title aside, I would hardly call that live-action cross-over thing from a couple years ago an "adaptation". Any actual resemblance to the real "Crisis on Infinite Earths" was purely coincidental and probably an accident.
I know I lost the war on the whole "It's just a title, maaaan" thing ages ago. Don't care; titles create expectations, if you're going to go completely off the reservation to the point where there's NO resemblance, give your story a different title and add an "Inspired By (________) from the DC Comics Series" card during the opening credits.
But yeah, no, that show wasn't an "adaptation" of Crisis, any more than BvS was an "adaptation" of "The Dark Knight Returns" simply because Batman had an armor suit and had a scuffle with Superman. Merely "inspired by".
Sorry, I am rather pedantic.
