These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternative Character Interpretation: Was Tim a devoted environmentalist who gave himself to a worthy cause, albeit to an extreme extent? A broken unhappy individual desperately clinging to the only meaningful thing in his life? Or a naive self-involved fool who crossed a line no one should and paid for his mistake with his and his girlfriend's life?
"Funny Aneurysm" Moment: David Letterman jokingly asking Treadwell if he isn't scared the bears will eventually eat him. Which, of course, they did. This interview was removed from the DVD release of the film because Tim's actual death made it seem like the audience was laughing at Treadwell's impending demise.
He also made several claims that he was a wanted man and that the park ranger helicopters that flew overhead periodically were meant for him. As is, the rangers didn't know he was out there at first and when they found out, they weren't exactly on a manhunt (although they were concerned about his safety and wanted to convince him to go home).
Jewel explains at one point in the film that Tim was bipolar; this, coupled with the fact that he refused to take antidepressants or anti-anxiety prescriptionsnote (he had tried medication before, but he couldn't tolerate the disturbing "deadening effect" it had on his emotions), undoubtedly played a part in his poor judgment.
