Saw this a couple of days ago on D+.
I'd plunk this solidly in the middle of Marvel movies. I liked it better than some - Eternals, Iron Man 2, GoG 2, and didn't like it more than some others. A solid B+ as far as I'm concerned.
Yeah, I can see where some of the criticism is coming from - there was just too much going on - too many cameos and characters that really weren't all that necessary. Sure, the bit with the Guardians is fun and all, good punchline and the goodbye scene is funny, but WOW, talk about dragging it out. Yeah, we get it. Thor sad, Quill wants to leave.
I think I would have preferred a tighter movie with about half as many characters but a lot more time with Thor, Jane and Gorr.
I'm sure Love will be making appearances again before too long.
And, I do agree that putting Korg and Luis in the same scene would be freaking hilarious.
