★★★★ Nikita is a story idea which, like the heroine, will not die. It began as a French movie, had a brief flurry as a TV series, and has returned as a more successful series with a few twists, turns and buffed bodies that bring it up to date. And there is the inevitable computer genius, Birkoff. Nikita was recruited to do ‘‘special’’ work for a dodgy organisation, but has gone independent. Cool.
