Both both VH1 and MTV  have been using Richie Unterberger’s excellent long Beatles biography as their Beatles biography they both used to not have a very good biography of The Beatles.
The Beatles own documentary The Beatles Anthology
The great 1982 Beatles documentary,The Complete Beatles
And any great reputable accurate Beatles biography would debunk this ludicrous,stupid myth and I have never read or heard any legitimate serious rock or general music  critics and writers describe them this way for very great reasons!.
