Personally I feel that ANY film that is critically acclaimed and deals with serious subject matter should be off limits for the RT experience. Why? Because it's simply not funny material to poke fun at.
I would agree with the second half of that point, but disagree that the 3 movies you mentioned are in that category. One is pure science fiction/monster movie, the next is fantasy, and the 3rd is supernatural. A movie like Witness is where I would put the line.
Humor is totally subjective and determined by the beholder. I respect your stance and am not trying to sway you or anyone else. I simply saying that I feel there is a line to what is funny and not funny with motion pictures, and some of the selections lately have crossed that line (Saw, TTT, The Sixth Sense). I'll continue to buy RT because I am a fan, but it's been disappointing as of late and I hope the trend to riff war movies or a child combating their inner demons passes soon. Surely I can't be the only person who feels this way???
The war movies they have done lately have been all fantasy, not to be taken seriously. 300 was about as true to history as a road runner cartoon.
I am curious to see how they did with the 6th sense, that's the only one I'm not sure of, Unbreakable would have been my choice for an M. Shamalama movie...
There has been a slight trend to more "dark" movies lately, and I do hope they get back to more movies in the "stupid" category.
