The best way to watch EEAAO is knowing nothing about it. Its never going to be what you expect and if you go in expecting too much, you're likely to be disappointed. Sounds very much like the hype might be why you feel the way you do.
Personally, I love it because there is more than just weirdness to it. It manages to have quite deep and emotional moments that fit naturally amongst everything that is going on.
For example:
spoilers
When Evelyn learns that breaking up with Waymond would have led to a 'perfect' life and the complexity of her feelings around that, only to be hit moments later by the gut-punch that Waymond would have been far more successful without her too. After that, how can she not regret the decision which led to them both being stuck doing laundry and taxes?
It's this deeper side and the depth and realism of the characters that really elevate the movie for me and lead to me still thinking about it months later. That's why it's more than just a cult hit IMO, but you aren't wrong if you disagree.
