On Sherdog and elsewhere, I have never seen such extreme views on this guy. People either love his tactics or hate his conservatism.
Personally, I love him. He proves that perfected TMA is superior to cut-and-paste, watered down combination of rudimentary Thai boxing and wrestling that 99% of UFC fighters use. I definitely see BJJ losing a bit out to Karate in the long run as Machida keeps winning.
