I remember the blue beam of light was done enough in both MCU and DCEU movies to the point the writers of those films made jokes about them in interviews. I don’t know if it was the first one to do it but Avengers 1 famously had the evil blue beam of light going from ground into the sky in the climax.
Soon after superhero movies stopped doing the blue beam of light but wound up doing another bizarre cliche, the ending where two groups meet on a large open field of battle and then charge at each other leading to immediate one on one warfare. Captain America: Civil War is the first one I think of with this ending but other MCU movies from that era also wound up doing this as well. Note I’m not talking a generic one on one fight at the end like Wonder Woman, but it has to be a half-dozen or more people on each side charging at each other.
So which cliche wound up happening the most?
