Pretty self-indulgent but then what Tarentino film isn't? Very funny in places and held my attention despite the slower pacing. As mentioned by others, the set-pieces are more concise in this second part as it is far more dialogue heavy/driven. A tonal shift that I think would have been more noticeable had they trimmed it to a single film . Nicely off-kilter conclusion.
The slowly winding tension makes this a better film than the first. It has the confidence to rely on its characters and dialogue, and these carry the film through with ease. The fight scenes are made more concise and more personal, and are all the better for it. Beautiful style and physicality.
