Iron Man Matches - Well, there's only been like four or five Iron Man matches in history and every one of them has been pretty great except for that Cena/Orton abomination at Bragging Rights '09, so may as well throw them all on one set.
Shane McMahon - Interesting. Hopefully Shane himself will make an appearance on the DVD and we'll hear about his perspective on things directly from him. A lot of potentially interesting stuff that they could delve into here (at least if they're willing to be brutally honest), especially since we know a lot less about Shane's happenings backstage than we do Vince, HHH, or Stephanie's.
Best of Superstars - Otherwise known as "Best Of Heath Slater" or "Best Of Zack Ryder's Matches That Lasted More Than A Whole Minute." Yeah, I'll pass on this one.
Randy Orton - Maybe.
Hardcore - Yes.
Divas Biography - Depends on the Diva, but this is likely a pass for me either way.
The History of the U.S. Championship - Yes.
The Usos - Agree with Just Kevin, they should wait at least another few years before releasing this one. I know they've been with the company for a good while now, but they only started finding success and a decent run as of late 2013/earlylast year.
The Best of RAW & SmackDown '15 - Yes.
Best PPV Matches '15 - Yes.
The Miz & Mizdow - They're seriously releasing an entire DVD of this one? This sounds like it'd make for a quick one-hour featurette on the Network at best. I dunno, if they release every single promo and segment they ever shared together, it might be worth it, but otherwise, no.
Stardust - Not even worthy of a featurette like above, let alone an entire DVD.
The Best of NXT - Not a fan of NXT, but should be a treat for those who are.
Unreleased Matches - Maybe. Depends entirely on the matches.
Total Divas Season 1 - And no.
