Based on the opinions of a Nintendo fan? Sure, I have no doubt that it could be underwhelming.
Based on people actually owning a PS4? Well, the like/dislike ratio on YouTube has greatly improved from the first State of Play with 91% of people now giving it a thumbs up. Personally, I've learned to manage my expectations so I enjoyed it as well.
I don't have an opinion. I was basing my comment on the comments I read on this thread. I'm still getting over how bad the last Nintendo Direct was to be bothered to have an opinion on Sony State of Play. I was just curious what the general consensus for Sony fans was.
