How can anyone blame New Day for that awful segment on Raw? Most of it was before they even got out there! That was a "Vince McMahon Special" segment that clearly was written to appease him and him alone and his weird humour. I felt bad for all involved, especially Gallows and Anderson who unfortunately seem to be the chosen comedy performers now.
New Day suffers because they're a comedy act in a company that generally doesn't do comedy well. They've got bad writers and a crazy old man "helping" with their material, and the more successful and over they got the less control they have over what they say because of all the meddling.
Also, how can they be expected to be so funny week after week. These aren't professional comedians, they're expected to come up with new material every week to basically sell cold to an audience.
