I can't speak to his defensiveness but there certainly is a lot of over-the-top criticisms of something most of us haven't viewed yet.
Am I disappointed with the screenshots of the VFX we've seen thus far? Yes. Do they "look like ass". I don't think so.
What I've seen, mostly, looks like ass compared to the work CBS Digital did. Saying they look better than the season two DVD's is a no-brainer. They could've simply up scaled the DVD's and it would've looked 'better'.
CBS-Digital set the bar for how the effects should look and HTV-Illuminate looks to be falling far short of that benchmark.
