Nah.
That first and last chapter were fantastic but I spent much of the game waiting for things to get good. Combat was as good as ever and when a character from U4 showed up, things perked up but it felt far less ambitious and more "paint by numbers".
U4 was slow paced but I spent so much time in awe thinking "this is the best game, ever!" that it didn't matter. I'd say LL had the better payoff and the bigger stakes while U4 had the better journey.
