I like it, probably in a fanboy kind of way. It's certainly not better
than the regular D IMO, but I like
it and its use in that episode
. However... looking at those pictures posted here earlier... It really is pretty terrible.
The only thing that I don't think looks all that bad is the third nacelle. It's kind of odd, and it looks better without it but it doesn't look as incredibly awkward as the rest of the additions. The way that phaser attaches to the hull makes me think of the Yeager kitbash... which is goddamn ugly.
Now, the REAL way to make a good refit is with the Excelsior/Enterprise-B. The B is my all time favorite canon ship. But that's a topic for another thread.
