My complaints (which need not apply to others, of course) - A lot of the main characters and plot lines feel the same. I can't tell you what happened in some books vs other books because they all (to me) feature listless males who drink Cutty Sark, enjoy jazz music, and have weird shit happen to them that they mostly tolerate while acknowledging that it is bizarre. - The style feels a little flat. It just kind of is. Even though the sentences can get quite long and windy and full of descriptions and details until you get lost, much like a sentence like this, my inner voice still reads it in a kind of monotone that I imagine resembles how the protaganist (if you could call them that) goes through life. The kind of prose that, if you're tired, will make you more tired.
What I liked - The casual surrealness. I complained about it earlier but it's also a feature. It isn't meant to transform the book into a sci-fi or fantasy novel, it just is what it is. - The lack of resolution. Too many books try too hard to wrap things up. Sometimes things just are. Which is also probably why I can't remember what happened in which books since they just end up being a series of events (think another commentator noted that). - The way things weave together. Not everything wraps up, but that doesn't mean they aren't connected. - Japan. I've lived there before, it's fun to read about characters and think "oh, I've been there!"
I don't think this accurately sums up my feelings, which I guess means there's actually a lot to unpack which is a positive sign, but basically I think if you can't get into Murakami, that's fine and isn't on you.
