The Hobbit in July 2007?

[Sir Kohran]

The LotR movies by Peter Jackson were made to bump up studio profits & flog popcorn to teenagers.

No, that's Eragon. The LOTR trilogy was ground breaking because it was capable of making profit and being deep, thoughtful and powerful in a way most movies don't bother to be.

but they can't be classed alongside the work of a literary artist like JRR Tolkien.

Of course not. They're not books. They're not supposed to.

PJ's movies are for 3 hours with a pizza & a couple of beers.

Again, more generalisations. If this was all the movies were made for then they could have made Independence Day or Pirates Of The Caribbean or some other mindless flick. The LOTR films are much more than that.
