This would be a valid criticism except .... wait for it ... all those things are based in fact and actually worked. Reading a lengthy Esquire piece on the guy reveals that almost all of things in the film, including the AIDS fake-out, actually happened.
Must not have worked too well... dudes still in prison. Just saying. That said, the aids fake out was probably the best part of the movie albeit somewhat predictable. As soon as McGregor stated that he had been tested and was untouched I figured that it was some sort of ruse.
I sincerely hope you're kidding. For the record, it's this exact attitude that kept the movie from getting released for quite some time. Really sad.
Whether it is sad or not, it reflects the mood of the population at large regarding such matters. This movie is not just about gay characters, which I think are fairly well accepted nowadays. It includes quite graphic and over the top gay sex scenes which I think, for the most part, still creeps people out. I watched the entire movie but can admit that I winced more than once. The boat scene... just wow.
Honestly, I probably wouldn't have rented it had I known a bit more on the subject matter. Here's the DVD description from Redbox:
Jim Carrey stars in the “outrageously funny” (ROLLING STONE) true story of a spectacularly charismatic con man’s journey from small-town businessman to flamboyant white-collar criminal, who repeatedly finds himself in trouble with the law and on the lam – all in the name of love. Co-starring Ewan McGregor, I LOVE YOU PHILLIP MORRIS is an unbelievably true comedy that’s being called “the best performance of Carrey’s career” (VILLAGE VOICE).
I guess I should have known as soon as I saw the word flamboyant.

And yes, "I Love You Phillip Morris" was one of my top 10 films of 2010.
This is not at all surprising. You seem to like material that makes you use your "gay matter".
