A good continuation and finale for TV series. It could have used a bit more time for a fleshed-out epilogue (at the least there is 1 romantic line that needed a resolution), though. And from technical perspective... It kind of started explaining things, but in the end still made little sense, especially from security perspective. In fact, considering the purpose of those trees, it does not make sense that this world ended up with no one remembering anything. And the spirit thing was not explained in the end, at all. But, at least, the story is complete now.
