(This only applies if you have watched the original series before watching the "New Translation" films) If one has seen the original than this is a definite welcome addition to it, it adds better animation and sound whilst also making the ending far better. The ending of the original is, well, let's say abrupt to put it charitably. This gives it a much better sense of closure, and for that (despite a few important cut scenes), it is the best of the three "New Translation" films. The obvious failings are the clashing animation styles due to the odd choice to only overhaul the animation for half thefilm and leave the rest as it was previously.

The story is intense, fast paced, but lacks the emotional impact of the TV series.
Haman is morore decisive and threatening, until the conclusion.
The new ending is more unambiguous, which depending on your tastes will impact your enjoyment positively or negatively.
