When I heard about this I was moderately excited as I'm a huge fan of Superman, GOTG 1&2 and Slither so I know the potential for something decent is there. Definitely not into it after the trailer. Too much cramed into one movie. I kind of want to watch as a curiosity.
I still don't understand the draw of packing as many characters, nods, references, cameos, fan service and storylines as humanly possible. Almost always occurs at great detriment to the main story and characters. I'll take the Donner deep dive over the "garbage plate" type film any day. Also filmmakers and content creators need to stop catering to the 2 second attention span and the need for constant escalating overstimulation.
