I will not say that it's a great or enjoyable MCu movie but I deeply hurt by bad CGI at some points, poor story lines and unnecessary family reunion and dialogues.
If we discuss about technical aspects then there were many flaws. SHIELD is operative in same area where widows are working still they don't know where they come from. They have their own data station yet they don't know that a Russian is functioning a whole space station there.
No one cares that there is a prison escape untill the helicopter comes close. Like come on its helicopter you guys should have seen it from far.
Mother doesn't look for her daughters yet she stored all the belongings hoping their daughters will come and they will go on mission.
Last action sequence was gravity defying. widow who got trained same as Natasha jumped from building got her ankle twisted and died and here Natasha jumped from above the sky and still fighting.
I like that Natasha was different but making her like Thor figure was something that is not justifiable.
Plus points were cinematography and some action sequences.
Some dialogues were good.
There were signs of some bad editing.
