Well, it could have been worse. Like Absolutely Fabulous the movie bad or Mrs Browns Boys D' Movie bad.
It could have done drag-in-celeb things like bring on Ali G as a guest rapper (because there is a guest rapper). Or have Ricky Gervais' David Brent of The Office in an encounter with Steve Carrel's Michael Scott of The Office (the US remake), which would have been like old Spock meeting new Spock in Star Trek.
As it is, in its own BBC-TV-show-afterthought kind of way, David Brent: Life on the Road is more in the league of Alan Partridge: Alpha Papa - a mildly satisfying final encore for a prickly Brit comedy character that its creator will never top.
One problem with Brent's encore, though, is that he's come back solo. The other characters of The Office aren't involved. Neither is the show's co-writer Stephen Merchant.
So just as Gervais has left his old band behind, his Brent is out solo with a bunch of hired hands who can't replace the chemistry of old.
