If you're going to write a negative (or a positive review frankly) of a show, concert, or anything else, as long as it's not just "That sucked" "It makes me want to kill myself" or overly snarky I can generally respect that person's opinion even if it's not in direct agreement with my opinion. As long as that opinion is backed up with rationale and levelheadedness, very common in the Phish community.

That being said, this was an Average-Great blog post at best
