Good film, bad director where it counts
This is a good movie building up, but it fails in its key moment.
SPOILERS
There should have been a CEAR explanation of how Phil was killed.
It is the pivotal moment in the story yet is handled cryptically.
I had to come here to read that the kid gave him the rawhide of a cow that died of anthrax, and Phil had just cut his hand so he would get poisoned. How convenient.
Wtf.
They could have shown it much better, like Peter using gloves to give Phil the hides, or carefully handling the contaminated cow to get the hides for his studies, him intentionally causing the cut on Phil's hand, or whatever, him reading about anthrax in his med books at least.
We only get a shot of the kid handling the finished rope with gloves after Phil is buried. Not even rubber gloves, no, cowboy gloves. It is so unclear I thought it meant that Peter wanted to become a cowboy like Phil now, following his footsteps.
The whole sequence is handled poorly and is not understandable just by watching the images.
You need to know the story from the book to get it.
Shitty directing, that is what this was.
