Watched it last night. Wouldn't put it anywhere near "worst movies I've ever seen" not even sure it'd be in the top 3 worst marvel movies (Iron Man 3 would take all 3 spots), but it'd definitely have to go on the list of contenders for 4th.
They just seem to have used magic as an excuse to put in lazy plot devices and give up completely on story building or having any kind of cohesion, and the whole multiverse thing has become too silly too quickly.
I can't even do a list of things that made no sense with this film because the whole thing right from the very first scene is a complete mess, and it's impossible to engage or invest in a film when it starts off by throwing such a level of garbage nonsense at you that its impossible to swallow.
I think the complete waste of the cameo xmen/fantastic 4 was the most annoying part, or possibly that at the end of the film I'm still not sure at all what the actual point of Wandas plan was? She wanted to be with all her children in every universe at the same time or something? How would that work exactly? Where were her children in that universe strange had destroyed then? Feck off
It was basically a 2 hour long rubbish episode of Rick & Morty
