I was so impressed with Metroid Dread, like seriously. As a long time fan of the series I was going to buy the game anyway but it's just such an impressively polished and put together piece of art. I was deeply impressed with it. I'm also a big fan of the direction it's taking the lore into.
Edit: can't get the spoiler tag to work so I just removed the second half of my comment sorry
I didn't mind them that much, I viewed them more as a puzzle than a combat. It helped break up some of the run and gun of the rest of the game and you always knew you were getting a cool ability when you got through it.
That said though I'll admit the last couple EMMIs did give me a really hard time with many, many resets. But I did get through them. And once I even managed to get the perfect parry and escape after getting got by the EMMI and it was extremely hype.
I didn't see it so nothing was spoiled. I'm trying not to read the guides but I do want to know when the last PNR is in case I need to explore a little.
