You have to agree some of the vitrol TPM faced -was- due to some seriously unmeetable expectations (understandable given SW's legacy up until that point). But as the emotional responses give way to more reasoned analasis, more people are giving TPM it's fair due.
For my part, what makes any one of these 6 films great makes them all great.
To me, this is all one big 12-14 hour film, and I think Lucas has accomplished far more than most other film makers will ever hope to do in their own lifetimes.
They aren't perfect, but way better than most in my opinion.
