So for me I enjoyed Season 2 more than I did Season 1 because it stepped away from much of that, the characters are still the same, except we don't have to go through their backstories and faux betrayals, instead we can just enjoy them for who they are.
One issue with season 1, was the bloated character roster, but for season 2 you can't just Thanos Snap away most of the bloated cast, so it has to find ways around this. The 'cheerleading squad' is left behind so we get a tighter focus on the characters, and many of the still expansive cast of characters that do still follow along for the ride don't get much screen time anyway so that it focuses on the main story, the new characters, and still having the small core group members to tie it all together.
As for the series itself, it started strong, you normally expect events to build up, but this just threw out that convention and announced its arrival. after that, it did start to go off the rails when they went to the land of the spirits, for me this felt like the weakest part of the series.
After that we got to the time travel part, and I seem to be in the minority in that I liked this part of the series, in fact I would go as far as saying that for me, this was the strongest part of the series.
This is where it actually focused on the story, on unravelling it's 'mystery' which some of it you could see through anyway, but... The focus here was tighter as it got away from a lot of the background noise and the excessive cast roster, instead for a good portion of it we focused just on the two main characters.
It's easy to see why a lot of people don't like this part however as Anos tends to take a backseat and isn't the main focus, and also as a result of that, we don't see him be OP and Deus Ex his way out of every situation with a condescending wisecrack.
But for me, this section was worth it because it allows you to have that 'pay off' at the end.
And then we get to the end, and I won't spoil it, but I can understand why some people got confused with some of the things that happened, the different terms and concepts that this series brought in or expanded on, but it probably helped that I binge watched this series across two days, otherwise I might have forgotten a lot of the jargon and otherwise seemingly meaningless details if I had watched it over a period of weeks.
In short, this in my opinion is better than season 1 as it was able to stand out more from the crowd, but it still has its flaws, and I don't think anyone would consider it a masterpiece.
If you liked Season 1, you should like this, although judging by some of the reviews, I wouldn't take that for granted. If you didn't like Season 1, or don't like this genre, then this won't change your mind on things.
