You've seriously never seen a movie reviewer talk shit about Adam Sandler movies?
I don't really follow film critic media that closely, maybe because there's generally more options available to me in how to see a film and less cost of entry. More interested in the production elements, if anything.
I don't think that would sit well with me either though. Sure, lambast whatever [insert medium] falls terribly short, but probably not in the manner Rosenburg kicked off. Doesn't matter if it's a film like Die Hard or one like 50 Shades of Grey.
Again, a lot of people on GAF have issues with folks like Gies (and certain developers) having similar behavior. Not sure why suddenly it's all well and good.
Edit: For the record, I do agree with the average at this point and much of the dialogue within the reviews themselves. Has nothing to do with that.
