Thanks to this thread I watched Johnny Got His Gun on Youtube last night as I liked the sound of it. However, I was hugely disappointed.
The main problem for me was that the film was not made well. The acting was absolutely terrible and more wooden than Sherwood forest. This didn't help the contrived screenplay sound any more convincing. The directing was also quite messy with failed attempts at surrealism. My guess is that Dalton Trumbo may know a lot about writing, but nothing about filmmaking.
It's a shame because I love the central idea and I liked how we heard the thoughts of Johnny throughout. Some moments were quite sad and poignant such as the flashback to when Johnny left his girlfriend. The film was just not executed well. I think if David Lynch did a remake, then this film could be quite something. I was unfortunately left unimpressed.
Just watch Metallica's One video, it's 10x better than the movie The editing in that video makes the movie look so good when I finally got to watch JGHG it was a complete letdown and now disturbing at all.
For me one of the most disturbing films I've ever seen is an Italian film called FISTS IN THE POCKET directed by Marco Bellocchio, his first film, and released in 1965. It's probably too tame for most folks on this board but the story is creepy and intense and Lou Castel gives an amazing performance of a someone who slowly kills members of his own family.
