Spoiler-free review
I watched this movie with my brother while we were traveling, I would say it’s a pretty good movie. I can watch it a second time as well. There was comedy and some of the scenes were presented well. we didn’t get bored at any moment.
Spoiler
I would say in the end 22's spark was just regular old living.
If you see moments in the movie from 22's point of view some of them like eating pizza, and watching leaves falling in the breeze these are the moments she wanted to feel, which she wasn't able to fill in Great Beyond
On the other hand Joe believes that life has some purpose like you have to be successful but afterwards spending time with 22 on earth I think his point of view also changed.
I think for me the movie perfectly showcases that sometimes you have to notice your surroundings as well instead of constantly running in a rat race or focusing on any particular result you also can enjoy the process
