Truly this must be trolling. I refuse to believe that people are actually equating hearsay with first-hand experience. If this is true, we are currently looking down toward the point where we imagined peak stupidity would be.
And as for "regurgitating other people's opinions", there is a slight difference between "I repeat these points someone else made, because based on my experiences of the topic at hand, I agree with them." and "I have no direct knowledge of the topic at hand other than what someone else has told me, and since I have no first hand knowledge, I can't be sure that I would agree with them". The second statement is not necessarily invalid, but it's a pretty poor substitute for first hand knowledge, and terrible for subjective judgement.
It's fine to read film reviews and decide that a film is probably not for you, but you can't make an informed critique about it. Sure, you can have an opinion, but it's not an informed opinion and you have nothing to contribute in a discussion of the film's qualities.
Also, it's kind of hilarious and sad that someone who refuses to spend 2-3 hours seeing a film they might not like spends a 2-3 times (or more) that amount of time trying to argue the points of said film.
