BACK WITH THE EX
New series ★★★
Wednesday 9pm, Seven

Does anyone seriously want to get back with an ex? Apparently so, and while the premise is the stuff of nightmares for most of us (and there's a chance things will indeed go pear-shaped for everyone by series' end) for any student of human nature, watching couples negotiate the process is fascinating. A couple of the men have clearly been living with a fantasy of what their ex was like and are now confronted with the reality; while one woman seems to have absolutely no appreciation of the hurt she caused her high-school sweetheart.

AMBULANCE
New series ★★★★
Saturday 7.30pm, Ten

The Brits make fly-on-the-wall documentaries exceptionally well and Ambulance is a terrific addition to the lists. As the name suggests, it follows the work of London's paramedics from control room to streets to hospitals, and it's a compelling, moving and often entertaining journey. As well as the nitty gritty of saving lives we also get great insight into managing the emotional load (their own and that of their patients) along with the sadly familiar story of a service that's desperately overstretched.
