To differentiate themselves from the Marvel movies, the DC superhero films decided to be s****y piles of unlikeable misery. However, they did end up using the same blue light beams. In Man Of Steel, all of Metropolis not smashed into rubble by Superman himself is vaporized by a giant blue beam.
No matter how many cool weapons the bad guys came up with, they kept coming back to the blue beams. They even showed up in Transformers: Dark Of The Moon. Think about that for a minute: It's a movie about robots that turn into fighter jets, Laserbeaks, and dinosaurs, and some a*****e still suggested, "What if we blew everything up with just, like, some big blue beam?"
Suicide Squad is a movie featuring 416 potentially interesting characters and one Jared Leto's Joker, and even that monstrosity manages to squeeze in three giant blue beams.
