Shorter is more accurate. Dennis Lawson is not far off from Mark Hammil's height. I was sort of surprised by that, whenever it was pointed out when the figure was originally shown to use the Luke sculpt.
I was disappointed at the time, but then found out he really was a shorter dude so yeah, shorter is more accurate.
I'm at the point, with this hobby in general, where I don't know if I care. I want these figures, but Hasbro's making collecting impossible right now unless you want to pay premiums to simply stay current, and forget about extras at this point. That's rough when you think the line itself is overpriced to begin with at Wal-Mart and Target, so things suck a bit.
It makes figures you already have that are pretty good in the solid/basics (sculpt, aesthetics, articulation, features, etc.) much more tolerable when it comes to things like height inaccuracies, or the wrong saber hilt but something relatively similar, and so on.
In contrast, it makes buying a new figure a matter of much greater scrutiny... Eyes out of place you notice more. Paint straying from the hairline to the face, you notice.
To me, Evazan's thigh strap molded to his leg is pretty ****** on Hasbro's part. That should be a separate part of the holster, not part of the leg. Non-removable vests, non-removable headgear, lacking basic details and featuers like a working holster (*cough*or no holster where there should be one*cough*), bad paintjobs, and detail inaccuracies like height not being consistant with the rest of the line, are all now things that get put under a microscope by myself for sure and I think many others as well.
It's the $5 Sandtrooper argument, to me. For $10, he's meh. You might buy one or two but you don't care about him because all flaws are noticeable. For $5, you're happy to nab one every week even if his helmet is green, his belt's ugly, or whatever the $10 price point did to make you "care more" about the little stuff.
