I dug this film but...

And my digging it was mostly for the actors and the concept. But I feel like the love story was very rushed because there was a disproportionate amount of time spent on the setup versus the bonding with Tulsa. I was also a bit dissatisfied with the ending. It seems strange to me that they couldn't come up with an alternative to sending him back to mars, like say, building a habitat structure on earth that simulates the low gravity environment he was used to until they could find a suitable donor for a heart transplant. Sending him back just seemed excessive.
