It's not a good sign when the best acting and storyline comes just from the parent characters when the majority of it is about the main characters. Neither of the main couples where very interesting despite the supernatural conceit of a mystical rain powered connection.

I find the psychic hearing/loss portrayed interesting in that there is more choice in it than the characters realize. It's appears to be a strong connection of some kind between two people that doesn't require mutual love and can be broken unilaterally as well. The maturity of the parents was amazing, from their break up to supporting the mom's new path in life.

From the focus on showing how psychic rain hearing doesn't mean a magic unbreakable love bond and can be platonic soul mates, it's so nonsensical to push the main characters Tai and Patts back together. Their only connections are the psychic rain hearing, that they are both man children, and the doctor being the biggest one between the two. It would have been better if they just broke up permanently and Tai learns to be a stronger person on his own than to get back with a emotionally volatile and physically violent guy who has a ton of issues of his own to work through.
