This movie sucks. From the opening scene right to the weak ending this is a bad movie. The only reason I have rated it it 4 stars instead of zero is because Benedict Cumberbatch is about the only one who manages to salvage anything from this poor script.

Where has Chavez suddenly come from?

She has zero acting ability and no chemistry what so ever.

She was injected in to the movie to tick boxes, nothing else.

The plot is a mess, the lines are absolutely cheesy and cringe.

This isn't a MCU movie. This is the ending of Wanda Vision turned into a movie with a bad script and some Sam Raimi horror thrown in as a gap filler.

MCU ended with End Game.

These movies are only made to tick boxes and for liberal pressure groups thats why they have zero plot.
