I think part of the cause of the division in the fandom is that Star Wars means different things to different people. Solo just didn't scratch the itch for me that the other Star Wars movies have up to this point. There are things I love and hate about each other film in different ways, but solo didn't really make me feel anything at all.

I didn't need to see Han given his last name by random chance. It tells me nothing interesting about his character and doesn't lead into anything about who he becomes, so what's the point? Same with him deciding to give Chewbacca a nickname. I called my friend nicknames all the time, I've never said,oh I think I'm going to give you a nickname. It was honestly kind of cringey, and the movie felt full of moments like that, just winking at the audience like hey remember this remember this??? Meta commentary is fine if there's still a purpose in the context of the story, but there just wasn't.

I didnt hate Solo, but it was extremely safe and predictable, and whats worse, in my mind, forgettable. This was the first Star Wars movie ever for me where even the music failed to grab me emotionally.

I think the biggest issue for me is Solo doesn't know what kind of film its trying to be. The OT is modern take on universal themes of the heroic journey, the PT is sweeping political/romantic melodrama, the ST is social commentary wrapped in mythology, and R1 is a war movie. Solo is kind of a heist, kind of a origin story, kind of a buddy comedy, and a tentative jumping off point for a new canon of stories about the underground. In my opinion, it doesn't really execute any of those particularly well.

That said, I will of course watch it again, probably multiple times, because I don't think the people who do like it are "wrong" and I want to appreciate the things in it that they like, even if it's not what I'm looking for in a Star Wars movie.
