The cancellation comes after both shows dropped to new lows in the ratings in recent weeks, with the Christian Slater action series sinking to a 1.8 among adults 18-49 (4.3 million viewers) on Monday night and “Lipstick” falling to a 1.2 (3.3 million viewers) on Friday.

Though the “Lipstick” number was an improvement on the previous week, the show’s ratings have been below the line for a while now, and sunk into the red zone after the drama moved to Fridays.

NBC’s expectation for the return of “Lipstick” was modest, but “Enemy” was considered an important show. A spy thriller with a grown-up budget inspired by the Bourne movies, “Enemy” received NBC’s coveted post-”Heroes” time period. That valuable Monday hour of scheduling real estate has become less worthwhile in recent weeks, however, as “Heroes” shed viewers — weakening the lead-in for “Enemy” and hastening its decline.

No word whether Monday’s episode will be yanked from the schedule, or if the show will solider on for a few more weeks, or what program will take its place. “Enemy” is currently shooting its ninth — and final — episode. “Lipstick” has shot all 13 of its initial order. Both are produced by Universal Media Studios; NBC had no comment.
