I hated the ending to Lost. In fact, the entire 6th series. Even now, thinking about it is a complete bummer. I feel for you if you're experiencing similar disappointment with ReMI.
ReMI's ending was about as close to perfect as it's possible to get, for me. Heartfelt, touching, sort of creepy and weird, with a dash of humour in the mix. I was sobbing. It's a shame it didn't work for you - but at least you got to enjoy Lost!
