Normal comics "of the day" were a far different breed than what we have now. My daughter loves Chris Claremont's original run on Excalibur and New Mutants to the point she may have read them more than I did at this point. They are challenging, but they do not ooze the "adult" content of mainstream titles. Sorry but today's Uncanny X-Men is far too sexualized to go into my 8 year-old daughter's hands. Between rampant oversexualization and the increasingly graphic depictions of violence the current titles are something she's just not ready for.
In fairness, Uncanny is an unreadable mess that no one should be reading thanks to that hack Greg Land.
And books like Booster Gold, Incredible Hercules, Generation Lost, and many others are no worse than the stuff I read as a kid and in fact are probably better for kids.
