Honestly kinda forgettable. I had to check the villain's name again to write this review. And I watched it about 3 weeks ago for the 3rd time AT LEAST. I didn't hate it while watching it, but it doesn't add too much. The main appeal is that Natasha Romanoff/Black Widow is introduced in this, which is good for later movies. Still worth watching if you've got time and want to watch all the Marvel movies, but don't sweat it if you can't.
