Hurry up and watch "Project Hail Mary" so we can talk about it!
Until then: no spoilers!
Edit: taking my own advice, I need to hurry up and read the book too!
marymessallI would like to and can't BUT I have read the book and am pretty sure the ending is the same?
Probably some other people read the book too, so I bet there are a bunch of us ready to talk about it already, hidden behind spoiler warnings for the others...
Scruffy looking packet herder@marymessall The ending is similar but not exactly the same. IMO the choices they made were good and it is an excellent adaptation. No significant changes as far as the plot goes. @mekkaokereke
