Is it bad that I have been laughing at the?suicides
Not at all, since some of them are intentionally funny (Toaster, driving off a cliff, etc.).
I love the idea that he could have been stuck in a loop for 10,000 years. I wish they had touched on it more in the film.
I like that it remains ambiguous about things like that. When films try to explain things too much, it saps the momentum and energy out if it's not done just right. I like that we have no idea why or for how long he was stuck.
