Kill Bill: Vol. 2
There are really not a lot of good movies with good sequels, thus the reason I rarely bother to watch them. This one however, was great from start to finish- it really had a full circle moment, if you may. Nothing more to say really, as most of the praise has been spent on Vol 1- just one note though- I'd say binge watching both the Kill Bills was worth it.
side note: that poster looks insanely cool
