Aquaman was terrible. I agree that I dont hate it as much as Suicide Squad, but it was really bad. The dialogue was cringeworthy and hamfisted to say the least. To watch that much screen talent be forced to act out that script was just painful. If I were ever to have the misfortune of watching it again, Id have to keep count of how many times a character called themself by their super hero name. It was like a bad "Im Batman" joke. Everything is WAY over explained, as though anyone going to watch the Aquaman movie has never read a single comicbook or even seen a sci-fi anything. I would say its worse than Batman vs Superman, but obviously the source material doesn't hold a candle to BvS, and the lead actors don't mail it in like Affleck and Cavill.
Just when I thought DC was digging out of their hole, they lay this egg. Im also still confused as to how Aquaman got a movie before pretty much any other JL member, especially The Flash. If they want to have him close it out with some time travel (if for no other reason than to give Superman the boot all-together) then that makes sense, but I have 0 confidence in them building an interdimensional timeline when they can't keep one straight.
