As addictive as usual. We're always dismayed when we've played the last episode, and can't wait for the next disc to come through. Although the plot is dramatic and at times unbelievable (unless you go in for monumental coincidences!), the show manages to keep you gripped from episode to episode. Suspend your disbelief, grab a beer and some crisps and settle down with this...but be prepared to watch the whole disc right through, no matter what your intentions for an early night may be!
