I was disappointed by The Leftovers. Some questions do need answers like how did Kevin get powers and what did it mean? With a show that finishes with a big question mark about the sudden departure, why bother introducing an extra layer of supernatural things and not explaining that. I am ok with no explanation about the sudden departure but to me not explaining supernatural Kevin felt like a cop out. Like Lindelof hadn't decided whether or not he wanted to give an answer about the sudden departure and gave Kevin superpowers, then decided for an open ended mystery, but it leaves Kevin's arc twisting in the wind. It's a good show that is frustrating because of its shortcommings
