I saw them live once and I think they were shite, that's how flippin' ubiquitous they were if you were living in Britland at the time.
This documentary is about their earliest years up to the huge Knebworth shows. Going from pub gigs in the arse end of nowhere to blasting out twat-rock to 250,000 people over a weekend.
Certainly an impressive ascent.
Still not a fan, but the film's definitely enjoyable.
