For me, it's Dark Shadows (2012). Was it perfect? No, but neither was HoDS and NoDS. I absolutely loved HoDS when it came out and I saw it in the theater, but I was 13-year-old back then an a hopeless DS fan, so of course I would love it. Now, being a tinge older, I see its flaws. If they had shot the entire screenplay, it would've been so much better. As for NoDS when it came out a year later (played as a double-bill with HoDS), I also saw it in the theater and really liked it, but found it somewhat confusing (again, because the entire screenplay was not filmed, and parts that were - like HoDS - ended up on the cutting-room floor). I still think it's an atmospheric film, but without the cuts it's far from perfect. So that brings us to DS-2012. After seeing (on-line) scenes that were cut, it would've been a greater film. Many did not like the comedic elements (at our local Wal-Mart, it's sold in the "comedy" rather than the "horror" section). But I found them - for the most part - a far more realistic element than what Dan Curtis would've brought into another cinematic reincarnation. I'm afraid if this late, great man tried it again, we'd just get another rehasing of HoDS, like he did with the '91 version and it would've ended up being a logic-missing piece of work (just as '91 did). DS-2012 took our beloved story and made it more logical - again, for the most part - and one could tell that Depp and Burton also loved the original series.
I don't deny that Dan Curtis did some great things with the previous movie versions; he did. In HoDS, he showed us what he originally intended for the Barnabas story-line. He was able to add all the Hammeresque gore to it so popular back then. In NoDS, he gave us a frightening ghost story. But in so many ways he wouldn't think "outside the box." (And, as I said, the never-filmed or deleted scenes would've done so much more for both films.) Depp/Burton, however, tried to move outside that box and from my own experience with their movie it worked. Friends of mine who always hated DS came to love it because of that film. After we initially saw it, they had tons of questions for me. Neither HoDS or NoDS, I would think, ever had that impact.
And don't forget, while HoDS and NoDS played maybe for a week-or-so in theaters, thrilling fans, DS-2012 played in them for almost half-a-year. It was still in theaters when the DVD/Blu-Ray started coming out.
