I get most of this but why is....(spoiler)
Why would there be a chalk written note, "this is the first time"? How would he know he is in a time loop to do that unless this is all about mental illness? And if it is about the schizophrenia, how would we know/see the interactions he was not involved in?
I also don't get why Michael 1 would just go on a complete killing spree that included Sarah and her boyfriend in the RV. I get that he was angry at those who betrayed him, but they never got there. AND they were lost too so how did Michael find them?
I don't need a movie to tie everything together in a neat package; I just hate when I can't reason out the little details for myself. Thanks to anyone who can explain this to me!
