Tarantino invigorated American film making in the 90s. You don't think Reservoir Dogs or Pulp fiction have more intelligence then something like 'Top Gun' or 'Three Men and a Baby' which was the commerical norm just a few years earlier? anything really popular will generate bad imitations. There's no way around it.
I think Tarantino, despite being personally repellent is a genius, but just like there is good naked and bad naked, there is good genius and bad genius.
While I didn't really like "Top Gun" I understood why people did and "Three Men and Baby", even though it contained Steve Guttenberg, was beautifully written and delightful to watch...although the original french version had me laughing so hard I couldn't breathe.
Neither one of those examples damaged or hardened the souls of people who saw them. At worst, they were forgettable. "Natural Born Killers", "Reservoir Dogs" and "Pulp Fiction" took film to such a dark place that only a snuff film could do more harm.
I'm not going to debate anyone's taste in film, that's not the point.
