I don't know if it was just MCU deprivation but this was one hell of a solid action movie and it's a shame we didn't get something like it sooner. There's a lot to uncover from Natasha's spy days and one outing just can't cover it all but they do their damndest here. Yelena is probably the best character and she gets the most laughs. I can see why they were secretive about who is behind the helmet in regards to Taskmaster but it's a tad underwhelming. The main baddie doesn't really get enough time and it's kind of the weakest element of the whole thing. Overall though you get Natasha being Natasha and doing all of her cool Black Widow stuff and some great interaction between the main characters. It's kind of hard to screw up an action film.
No mid-credits scene but there is a post-credits one that looks to be opening the doors on other Disney+ productions.
