I only got through the opening sequence and most of the way through hulk's section in the hulk/Kamala part before it crashed on me. idk why, but the controls felt a bit janky to me and I also didn't enjoy what I did play for the reason you stated.
Personally, I also felt the VA overall wasn't great for the main cast. Black widow and Kamala were the exceptions to this, but Thor especially, was terrible imo. Didn't sound like the GOD OF THUNDER at all and more like civilian #4 with slight nordic accent that comes and goes.
On the same page as you 100%. Man, Hulk is supposed to be this brute in constant berserk mode, but somehow even against the most mundane grunt he seemed pretty powerless. I didn’t once feel badass when playing those story missions. The run-of-the-mill combat, like I said, was very much a chore. I’ll wait til it’s $20 before I bite on this. Hopefully by that time they’ll change gameplay up a bit.
EDIT: Oh and you're right on about Thor's voice actor. It's like they walked down the street and said, "hey you! do a nordic accent!" and said "good enough" to the first person they saw. It's quite bad. I'd also be willing to say that Troy Baker as Bruce Banner was a bad choice too.
