Brazil was a great movie, edgy visually and story wise.
There was zero new ground broken with V, other than it's the first pro-terrorist movie since 9/11, well 2nd if you count Farenheit 9/11.
I love Brazil, no argument there.
I don't think V was pro-terrorist. V declared war on the government and attacked government installations and high ranking government officials. The government is a valid target in a war. Yes he secretly planted bombs, but when you're one against many frontal assaults don't work too well, Navy SEALS tend to be a bit sneaky too. As for new ground it's over worshipped, the primary goal of a movie is to tell a good story well and hopefully make some money in the process. Some stories require new ground to be broken, most don't. John Wayne never broke a lot of new ground, but most of his movies are still awesome.
