DBD8 has a fantastic main event and two very good semi-mains. The rest of the show ranges from total shit to barely mediocre.
DBD8 had the best overall "feel" of any iPPV IMO. It had sports-like interviews, with crowd members and wrestlers backstage, which hyped the main events, and a few other cool touches.
It also had a nice bit of booking, that worked most people on here IIRC (not me :P) with that "The Briscoes are stuck at customs" thing. There was another swerve with the Cheech 'n' Cloudy false start too.
It's my favourite iPPV, closely followed by FB10. Not a fan of the other iPPVs tbh, excepting the markworthy re-debuts on a couple of them.
DBD also had ROH's only good DVD cover of the past year IIRC.
Don't know whether it's his best or not but it's certainly the best ROH have had since the take over.
You could barely see the match-listing on the back and the whole thing was really cheaply printed, to boot. It just looked like a homemade cover to me. I'm not saying that there haven't been a lot of other terrible ones this year...
