In the lull before the total heaven that will be the beginning of the second series of Mad Men on 10 February (BBC4, 10pm) comes Generation Kill, an HBO drama about the 2003 invasion of Iraq (Sundays, 10pm). The series, based on the book by the Rolling Stone reporter, Evan Wright, who spent time embedded with a unit of US marines, is the work of David Simon and Ed Burns, the creators of the Baltimore cop show The Wire, a combination that has got a lot of people very excited.
Not me. For one thing - and yes, I know full well that this is the television equivalent of confessing that I don't care for Philip Roth - I've never managed to become a swooning devotee of The Wire though, God knows, I've tried (perhaps it's just that I don't have as much free time as some TV critics, and thus cannot give myself over to watching box set after box set in a desperate bid to understand what they are all bloody well saying). For another, I'm not entirely sure that the time is yet right for Iraq dramas, for the blindingly obvious reason that we are still in Iraq. The thing is not over yet and, until it is, I find extreme realism of the kind that Generation Kill so gleefully peddles pretty hard to take.
Generation Kill is supposed to look "more real" than any war epic we've ever seen; one of the cast, Rudy Reyes, is even a former soldier who took part in the 2003 invasion. So, what we get are lots of men who all look the same, and talk the same: speedily, and in an army jargon no civilian can hope ever to understand.
They are not good men, but nor are they bad; they are simply doing a job, at the mercy of their often incompetent superiors as much as any vengeful Iraqi. They are bored, and desperate to "get some". They are full of machismo, but they also have a softer side; one, predictably enough, is moved to mention the Geneva Conventions when his commanding officer instructs him to send a bunch of surrendered Iraqi civilians back in the direction of the death squads they were attempting to escape. They believe that Evan Wright is there to record that they are "baby killers and mama rapists", but they're keen to impress him all the same. They like porn, J-Lo and pizza. They dislike soppy letters from schoolchildren who salute them for their bravery.
What Generation Kill does well is all the farcical MASH-style stuff. The unit's first injury was the result not of shellfire but of an exploding espresso maker; its commanding officers soothed their men, pre-invasion, with a vast delivery from Pizza Hut in Kuwait, which was just as well given they were expected to enter Iraq with only one translator between them.
But such moments, sparse in episode one, are likely to become even fewer once they get to Baghdad. And then what? The narrow focus of the action - we don't flip back to politicians here, or to the folks at home - means that we must come to care about these men inordinately if we're to stick with their girl-obsessed banter, and I'm not sure that they are likeable or complex enough for that to happen. This, however, is less of a problem for me than its writers' lust for hyper-reality. The series wears its authenticity so self-consciously that, paradoxically, it often feels as phony and clichéd as some old Richard Attenborough movie; the behaviour of the wired Corporal Person (James Ransone) is almost cartoonish. I fear that I will be not tuning in next week.
The same goes (a quick postscript here) for Friday Night with Jonathan Ross (10.35pm). I watched his return through a small gap in my fingers. God, it was embarrassing. Ross's tactic, post-apology, seems to be to turn up his sycophancy level a notch. Result: it now sits even more awkwardly with his fart jokes than before. "Tom Cruise, you are the greatest actor ever, I love your work, I think you are so handsome I could kiss you. But tell me: do you break wind in bed?" I paraphrase. But you get the (gruesome) picture.
