Speaking just for myself, I found Kill Bill 1 hilarious. I haven't seen a lot of kung fu movies...so Kill Bill to me looked like a "live action anime" movie. I found it so over the top, in gore, in silly lines, and in the simple (hole filled) plot that I couldn't help but enjoy it on the level of a sendup, or guilty pleasure.
I can't answer charges of self-indulgence or "why was it good?" I guess that's because in my mind, it wasn't really good. It was bad. It was deliciously, hilariously bad...and it really was meant to be that way.
As for you 'not getting it,' that's not a phrase I'd use. It suggests that there's something wrong with you, or that you're lacking something that those of us who enjoyed the movie got right, or possess. That's not really true. Kill Bill is just a very limited aesthetic, I think. People will tend to either find it great fun and love it...or find it inexplicable and a waste of time, and hate it. What precisely defines how a person will react to it is not something I care to speculate on. It's not just an appreciation of "bad movies." I know people who love Plan 9 From Outer Space...who guffaw at every episode of MST3k and still dislike Kill Bill.
I realize none of this will do much to relieve your distress and/or frustration over the movie's inexplicable appeal to a fraction of the population, but all I can say is that some people like it...and some don't...and that's pretty much that. I can say why I like it, but I can't make an argument that those qualities exist in any kind of objective reality that anyone can see and appreciate.
The happy news is that, having identified yourself as a Kill Bill Disliker, you can now refuse to spend any more moments of your life having anything to do with it.
