1) It's hard to tell what is real reaction and what is production reaction in WWE these days.
Agreed. In spite of the fans that 100% buy into what WWE is selling them and think the product is genuine and pristine (basically, the anti-IWC), WWE clearly tampers with crowd noise, especially on SmackDown where they tape the program days in advance and edit it into the product they want to convey with their talent in terms of face and heel. It's most obvious on guys like Roman Reigns and Kevin Owens, where crowd reactions are completely different on Raw and SmackDown. However, they also clearly manipulate crowd noise on Raw as well, by cutting the crowd mics when the crowd isn't giving them the response they want, as well as at times pumping in cheers and boos into the feed.
That alone makes it really hard to gauge what the true reaction any crowd is giving any particular wrestler.
It is even moreso with VV. Being their gimmick is of the Vaudeville and silent film era, it's really hard to tell whether creative is playing off that by silencing the crowd (and, being that they're a villainous group (badumtss), they shouldn't be getting a lot of crowd noise anyway), or if they're just not connecting whatsoever and it's a dead crowd.
What makes this even harder is the Vaudevillians is a "made for TV" gimmick, with all of the production that goes into their gimmick, it looks fairly natural on TV. However, from what I've read online, those people that have seen it live, whether at an NXT show or main roster, it's weird and not easy to connect with at a show.
2) I'd rather that than them getting cheered, so there's still hope they can create heel heat, which is pretty much impossible in this day and age
Another area I agree. Let's look at the division to this point.
New Day - an antihero(ish) group that really has made a turn towards face (although they still have heelish tendencies)
Enzo and Cass - outright babyface
The Dudleyz - outright heels
The Usos - faces that have a mixed crowd reaction
Lucha Dragons - faces that have been criminally misused as a tag team and appear to be headed in separate directions
The Ascension - heels that have been criminally misused from the beginning (never should have been altered into a cheap knockoff of LOD) and have jobbed for so long they don't have a shred of credibility left
Social Outcasts - who knows what these guys are
LoN - outright heels, but rumors are they're about to be broken up entirely
Golden Truth - outright babyface comedy team - but is it ever actually going to happen, or is this a several month-long cocktease?
Primo and Epico - nobody knows.
Gallows and Anderson - outright heels that will likely be cheered as faces. Attacking the Usos should have put nuclear heat on them, but instead the crowd cheered on the beating (once again, the writers not understanding what the fans want)
WWE really could use a traditional heel team like VV. Just not sure they're not going to get the Ascension treatment.
3) I'm turning in to a big VV mark I think they are great
I have mixed feelings towards VV. I have always liked the gimmick as it's unique, but I never thought it had a prayer of working on the main roster without getting a lot of help from creative via video packages (kind of like Primo and Epico are getting). You also have no idea what these guys can do on the mic - they don't talk, and the gimmick doesn't allow for much talking. Plus they debuted on SmackDown, and that never really goes over well.
I didn't like the idea of them being promoted in the first place, and I get the feeling they're going to die a slow death.
