way too much exposition, forced connectivity and fan service
Ive always loved the mcu for its feeling of natural connectivity. But that exposition bomb by mysterio midway through was too much and just bad...
that's without even getting into the fact that alternative universe mysterio was far more interesting than some disgruntled stark employees... He still couldd of ben bad, but just had it that he was going to sacrifice this earth to save his own dimensions...
that's without even getting into how the whole drone illusions kind of don't make sense. or his motivation. he already clearly has drones to make them.. but wants to get control of Starks program so he can.... have even more and make an even bigger illusion.... umm what?! But its actually so you can be the real hero! even though your crappy drone army couldn't stop most of the threats the avengers faced.. so umm what?!?!
