I understand where Jang is coming from, and all of his points (both subjective and objective) are logical, but my original stance on the set still stands.
Don't get me wrong, the '08 version was great for what it was. It took LEGO's then range of pieces and created an outstanding model. With that said, that Death Star is a set of its time. Certain things that are common place today (e.g. rounded everything) were not so normal back then due to a lack of pieces, not knowing how to do so, or hit by a restrictive budget (although the latter still happens today) and for that, I find it hard to critique the original for those specific faults. But for a set in 2016? I find it a little irksome.
Now I'm not saying the set is terrible or shouldn't have been released. It has a place in the LEGO Star Wars product range that darn near always needs to be filled and if you don't own the original Death Star and want updated figs, then the model is worth the price. However, if you have one or both of the previously mentioned points, I personally wouldn't advise you to get the set.
It's probably due to the Death Star (both the '08 and '16 versions) acting more as a playset than a hyper accurate representation of the source material. I personally don't find sets like this under the UCS mantle bad, but some other members of the LEGO community feel enraged by their inclusion.
