Hated this a bit less than other finales, poss because Russell seems to have decided that it's better to have no plot at all, than a derisory one to excuse all the character stuff - and I agree. If you're not going to bother anyway, then don't even try to tell a story. Just give us the emotional beats in the right sequence blah de blah blah.

The theme of regeneration as "little death" was nice; that last line was a bridge too far, though.
