I loved the movie but here are my issues (still a 9/10, best spiderman movie, best MCU project since endgame):
The big one is why everything is happening. The what is happening is great but why is half assed. Strange and spidey could have discussed the parameters of the spell, it makes both look dumb, especially Strange. It is hard to escape that they wanted all 3 spidermen there to face classic villains but how they got there was half assed
The final battle takes place at night and involves a sand guy (who I still dont know why joined the villain team) and a dark lizard guy
