I thoroughly enjoyed it. That being said, the movie does have some flaws (like some green screen shots) but not bad enough to impact my viewing experience.
What I recommend is that you go into it with low expectations (don't get hyped up by rumored cameos or potential storylines).
If you're a comicbook fan, you might as well come to terms that the MCU isn't always going to flesh out storylines or do justice to certain characters.
This movie did tie into past MCU productions (Norton's Hulk, Eternals & Falcon & the Winter Soldier) so maybe brush up on that before watching this movie (although it's not imperative, it just enhances the experience)
Lastly, the post credit scene is ominous but really vague so keep that in mind.
