Walter

Our eponymous hero is an amiable, bumbling cop with a sweet, posh daughter.  No prizes for guessing this isn't gritty drama along the lines of 'Line of Duty', which confusingly also featured Adrian Dunbar as a financially compromised detective.  That's the only similarity.  The opening scene may feature a worried-looking man going under a tube train, but this is a comedy-drama.  It's not a hybrid we've ever warmed to, because to carry it off requires first class writing which, in the days of marketing, ratings and pressured deadlines, is pretty rare.

Dunbar is a good enough actor to play hero, jester or villain and carry an audience with him all the way, and Alexandra Roach is likeable as his ditzy, sassy sidekick, but OMG they deserve a better script.  This involves a corrupt cop with a late-blooming conscience (like we said, not realism), and a murder which almost foxes the police, thanks to their undercover officer going awol.  It's sort of in the same spirit as 'New Tricks' - there are jokey scenes with the young, gay Chief Super, widower dad Walter and lovelorn Anne with her Welsh mother - but it needs a more even tone and tighter plotlines if it's going to spin out to a series.  There's potential for a nice light drama with a few laughs, maybe in a Sunday evening 8pm slot, but in the tough world of today's TV they may already have blown their one chance by an underwritten pilot, shown on a Friday evening in August.
