After watching it, I really enjoyed the whole movie. The tie ins to those of the past and how they work to fix the present. A few issues i see people call about is the whole bit with Captain Marvel vs Thanos, it was kinda odd. As someone said above, that they made her seem like the last hope/resort and you see her just slap the flagship as its nothing but I feel like thanos should've had just enough to up her when he had gotten the infinity gauntlet on twice considering the power it gave him.
Another thing i've seen alot is alot of verbal criticism on Captain Marvel, where some of the scenes didn't do alot. Such as you see her just tackle and destroy the Flagship in the final battle, yet in that from people calling it. The "Girl Power" scene where its the female superheroes showing up but she doesn't just fly right to the van how she did when she first arrived to the fight. Another bit I see alot is when she actually clashes with Thanos, Considering the powers the gauntlet gave Thanos in infinity war you'd think when he had gotten it on him twice the battle would've just gone one-sided by then.
I'd go inot this more but i'd rather not fill 1/3 of the page. All n' all it was a fantastic movie but nothings perfect and I see some of the issues people had.
