BBC One aired nearly five hours of live coverage of the river pageant on the Thames on Sunday afternoon, with one MP describing it as "low-grade, celebrity-driven drivel".
Poor sound quality and camera work were also damned, along with a description of the Queen as "HRH" rather than "Her Majesty"
Stephen Fry described the live coverage as "mind-numbingly tedious" on his Twitter page.
He tweeted: "Has the BBC ever presented a more mind-numbingly tedious programme in its history? "HRH the queen" said the first ignorant presenter. HRH?".
A BBC spokesman responded to the criticisms, saying: "We're very proud of the quality and breadth of the BBC's coverage of this extraordinary event."
Fry later added: "Don't get me wrong peeps, I'm not saying this in relation to ER II's jubilee - just expected better of the beeb. Didn't mean to upset anyone."
Former Today editor Kevin Marsh wrote: "Am I being over-critical or is the BBC commentary lamentable?"
He added: "Why cut away from Queenie's River Pageant to watch that mindless Tess Daly nonsense... scarcely credible."
Tory MP for Reading East Rob Wilson said: "Seems we all agree on terrible BBC coverage. Low-grade, celebrity-driven drivel. How did Beeb get it so wrong?"
He continued: "Which is worse, the heavy rain falling on the flotilla along the Thames or the BBC's dreadful coverage of this Royal Jubilee event?"
