In spite of living a few minutes from a theater, having quality internet access and a Netflix account, and owning nearly 400 different movies (across ~700 discs if I assume my binders are full), I really don't watch movies often. Most of those discs were collected when I was in the Army and desperately in need of something to do. I don't know what the reason for it, but I simply cannot be bothered to see a movie in any venue among any company unless it is forced upon me. When this inevitably occurs, I often enjoy myself of course, but I think that I have, in part, reviews to thank.
I often know next to nothing about the movies playing at the moment. Not having cable combined with rarely attending movies ensures I don't even know what's coming out much less anything about them. Thus, when it comes time to pick movies, I generally look to see what is playing, look at the trailers for what's playing, then when one looks interesting, seeing what reviewers say about said movie. It isn't that I am incapable of forming my own opinion but rather that I am so divorced from movies that I simply have no opinion until I see the film. And since movie watching is so very rare for me, it stands to reason I ought to at least check and see if a movie was savaged by the wider press.
In terms of Movie Bob in particular, I would simply point that he, like any other professional movie critic, tends to reward novelty with more praise than it truly deserves while savaging banality more than is necessary. Like Yahtzee, after seeing a movie I tend to agree with his argument in a very general way even if I cannot get on board with the specifics. For example, while Transformers was by no stretch a good movie (nor even a movie I would see more than once), I found it to be worth my time to watch. If I took bob's claim literally, that I did not rally in the streets against this film would prove that I am somehow an idiot because the movie was so terrible at every level only brain damage could explain such a thought. I didn't think it was good, but neither was I willing to deliver a scathing indictment of everyone involved in it's production and eventual success.
On the other side of the coin, I found Scott Pilgrim to be the very epitome of over-rated. It was seemingly made for people like me, praise was heaped upon it by Bob (among many others) and yet I found the movie almost unbearable. I only sat through it because of a girl I had not seen in 7 years, who it should be noted was briefly my girlfriend while I was on leave before deploying to Iraq at the time, asked me to go to her apartment to watch it after we had dinner and drinks. I sat through that film for the same reason so many of my peers sat through Titanic when we were 14: because of the off chance I would get laid as a result.
What I guess it comes down to is that our different perspectives are to blame. As a child, I did not care about Transformers even a tiny bit (and I'm only a hair younger than Bob I'd bet) and thus I had no expectation of greatness from a Transformers film. Its trespasses were thus less grievous because I had no emotional attachment. By contrast, I loved the Predator, Alien(s), and the Terminator and yet each of these franchises produced movies that, were I a professional reviewer, I would have savaged at least as badly as Bob did Transformers. In producing a bad version of something I once loved it was as though I was personally betrayed. It is that personal connection that made my reaction so vitriolic, and I suspect the same could be said of Bob.
Thus, I do what I always do with such things. I take the basic gist of what they say about a film and pay attention to that. The specifics aren't terribly important because such things are often exacerbated by expectation and experience or unnecessarily muted by hard jading experience.
