An episode involving a plot centering around one of man's eternal questions - Does God exist. Add into the mix, impending armaggedon and an alien invasion and this initially promises much.
However, what you get is pretty much cliche, predictable, flat, fairly dull screenplay interspaced with moments that pass beyond the average. The real strengths of this episode, are the performances of the actors. Specifically, O'Quinn (Locke in Lost) and Rohm (Serena in Law and Order).
Its how their close bond forms on screen given the dire situation that provides any semblence of watchability to this episode. Otherwise, it would be a very shallow screenplay indeed. The only special effects of note are the aliens at the ending, decent if thoroughly sentimental. Overall, the story lacks any real drama. Tension is limited only to the mystery of the aliens and their motives and purpose. Conflict is only simulated and reflects the potential catastrophe that could happen. This is only held in the minds of us the viewers as it isnt projected enough, mainly through the dismal acting of the foreign heads of state.
The casting of "Cancer man" from the X-Files as the president on Doomsday watch does add an element of irony, but he is wasted esp. at the end, which is anti-climatic and shrouded in the the whole cliche and expectant happy ending which can be forseen.
I wanted to give this a 7+ as I really did enjoy the onscreen relationship struck by OQuinn and Rohm. The story is on a basic level interesting and logical to follow. However, the perky start gives way to a middle act of little drama and action, followed by a final act of silliness.
I disagree that this deserves a really low mark, but I know not everyone will enjoy it. I say its one of the episodes you take a chance on.
