It is a very action-packed dumb movie, with emphasis on dumb. Bloodsport has very awesome and advanced pieces of equipment which go totally unexplained. I wasn't expecting a lot of backstory to each character but when someone has such high-tech equipment and they are not aliens and they're set in the dceu that doesn't have anything that advance on the earth shown so far, it just becomes a head-scratcher how a mercenary has it.
People love Harley Quinn but she is simply too OP for no reason at all. Seriously she one person kills all those armed soldiers in her escape without a single injury while standing out in the open the whole time. Starro can walk through builds like it didn't exist and but through all the concrete it is buried under but yet it somehow couldn't escape by itself all this time. For reals. Seriously are there really enough rats in any one small location to overwhelm and kill Starro like it did in the movie. With that many rats can anything else even live in that place? Starro can quickly regenerate from the interdimensional polka dots that seem very OP but somehow can't regenerate from rates biting.
The first squad that basically gets wiped out was so incredibly week that it just didn't make any sense other than to just have people to kill off right off the bat. Mongal is supposed to be one of the most OP characters in this movie and should be able to singlehandedly destroy that army, but she ends up just dying very quickly and easily.
