I got similar problems with many books that are considered great and classics. Can't read Tin Tin, for example and I'm sure Corto Maltese as well would work best as a medicine if I'm ever having insomnia. That said, most of the late 90's and even modern comics I'm having trouble with as well. 90's Marvel or DC, I'm solely checking out because of artstyle, couldn't care less about dialogue. Stories in them are often so convoluted that It's best to experience them by reading a wikipedia article about it instead or someting. Modern style doesn't oftentimes appeal to me either, the quip after quip followed by real life pop culture meme or reference is not my idea of interesting action or adventure story. I guess I'm kind of ruined by manga, which is super fast and effortless to read. Easy to follow as well, just start with volume #1 and you'll get the whole thing. That said, there are some older books I still enjoy. Usagi Yojimbo is a great example of 80's book that's still just as redable as it was when it was published. When it comes to European comics, Asterix for example, is still very good .
I'm glad to hear I'm not the only one that struggles with the writing of older comics. It's something I've been saying for years, but so many comic fans seem to be the exact opposite - preferring older material over newer.
That's really unfortunate you've walled yourself off from so many great works. I do know people who refuse to watch black and white movies or read older literature. Admittedly it can be a struggle to approach older material, but it's often so rewarding. On the other hand, life is short so if you aren't enjoying old comics why keep trying!
