The Tory MP said on Twitter during Sunday's live four-and-a-half hour broadcast of the Royal flotilla in London: "Low grade, celebrity driven drivel. How did Beeb get it so wrong?"
Mr Wilson was just one of many public figures left unimpressed by the BBC, with camera angles, sound quality, commentary and interviews being labelled sub-standard.
But the BBC, which attracted nearly 12 million viewers, has said it is proud of the "quality and breadth" of the coverage - fronted by Sophie Raworth, Matt Baker, Fearne Cotton and Tess Daly, among others.
Broadcaster Jonathan Dimbleby, who presents Radio 4's Any Questions and is the son of Richard Dimbleby - BBC commentator for Elizabeth II's coronation - was also critical.
He tweeted: "Dire reaction to BBC coverage of another great event. Am asked whether bigwigs have lost the plot. Good question to Any Questions. My father Richard would have loved this weekend. His coronation commentary touched the national mood then as it would now."
Others critics included the BBC's QI frontman Stephen Fry, who described the coverage as "mind-numbingly tedious", and former Beeb presenter Jonathan Ross, who dismissed it as "excruciating", "awfully patronising" and "nonsense".
