Call me Robert guys
I kinda agree with your overall sentiment than the actual points.
First, I really liked the movie. But I had very few expectations going in. You expected action with Natasha, but she's just not IronMan/Thor/Cap/DoctorStrange.. so I didn't expect much outside of what we saw the trailer.
The dad was played David Harbour, who you might know as Hopper from Stranger Things. It's kind of ironic since he has a tragic history as a dad in that show and he's so aloof here so it's a funny dichotomy between the two roles while both being dads. Also, he was imprisoned for many years, gained weight and was pretty much out of form.. Roughing up and stalling Taskmaster was the best he could do and it worked well enough. But the 3rd act was kinda mèh.
Yelena is a scenestealer. Just about everything she did was gold.
I'd probably rate this movie as a 7.
I would agree with you if pretty much every scene with Black Widow in the MCU thus far hasn't involved her beating up multiple people lol. I just wanted her to let lose at least once. The most we got was when she was in the prison trying to free her dad, and that was pretty meh.
Honestly he just wasn't funny to me. Natasha and Yelena together were much funnier to me.
