Maybe a few people hit theaters with poor presentation that ruined it for them. But I imagine most of the theaters with 48fps abilities would be newer high end theaters that are in the habit of keeping things up to standards.

I honestly think all the hostility toward 48fps has everything to do with fear of change. It is a normal human response to the situation, and we've seen it countless times throughout our lives, with every little change science, discovery, and technology brings us, there are always a segment of people who oppose it vehemently. From going to the moon, to manual transmissions, color TV, and cellphones.
