After losing their son, Adam (Cameron Bright), to a freak accident, Paul (Greg Kinnear) and Jessie Duncan (Rebecca Romijn-Stamos), are approached by Dr. Richard Wells (Robert De Niro), with a risky and illegal idea--to try "replacing" Adam with a clone.
In my way of looking at ratings, 7s are Cs. They tend to do as many things wrong as right. Godsend has some admirable script characteristics, a good to great cast and some very good technical aspects. But it also has negative script characteristics and some questionable directing and editing.
Overall, I believe Godsend is worth watching, so let's look at the positive points first. It's rare that filmic science fiction--and this is just as much as science fiction film as a thriller or horror film--tries to tackle "hard science" as exposition and motivation. Although Godsend also mixes some strong fantasy elements into its "twist" and the consequences that lead to the film being a thriller/horror picture, the basic idea is one rooted in actual genetics. De Niro is given quite a few mouthfuls of science-oriented dialogue that are fairly sound, and for my money, he delivers them well.
I'm a big fan of De Niro's, so I tend to be gracious in my evaluation of his work. But I could see where some viewers less enamored with De Niro overall might find his performance here questionable. It's certainly a bit different than normal, being oddly restrained and almost emotionless for much of the film. For me, that approach fit the character, given his profession and eventual revelations about his personality. The other three principles--Kinnear, Romijn-Stamos and Bright--were good in my view, but again I can see where some viewers could interpret their performances negatively. To me, however, all of the obvious problems stem from direction and editing, not the actors' work.
The biggest problem seems to stem from director Nick Hamm's comments about the horror/thriller genre. He has stated, "what was interesting to me about Godsend was that the horror and the suspense had nothing to do with anything supernatural or spiritual". Hamm isn't a very big fan of the fantasy aspect of horror, which to me, translates into not being a very big horror fan. This led to trying to create a horror film where suspense arises out of realist drama and psychological situations. The realist drama in Godsend tends to be very slow and relatively uneventful--just as one might expect from someone not really wanting to make a horror film. Psychological horror is barely approached. There just isn't enough that happens. There are two potential villains, but neither does much. It would be very difficult to call either "evil".
Kinnear and Romijn-Stamos aren't given enough to work with. They don't have anything very meaty to react to. Hamm seems too afraid to leave realist drama territory, at least in terms of the overall plot/action. That makes some of their "horrified" reactions seem shallow or false. Worse, Hamm doesn't seem to know how to cut horror films very well. Scenes go on far longer than they should, and occasionally almost seem as if we're seeing a bit of the footage either before Hamm said "Action" or after he called "Cut". A prime example of this is the scene near the end when Romijn-Stamos is walking through woods toward a shed.
Godsend is also one of the few cases where copious DVD extras may have hurt the film more than helped. The DVD contains four alternate endings, averaging about 12 minutes long each. These occasionally deviate strongly from the theatrical ending, but none seem quite satisfying (all of the more nihilistic endings that Hamm described on his commentary but which apparently weren't shot would have done the trick for me; I also liked the filmed tag suggesting a sequel). They all tend to drag on, an impression that isn't helped by the lack of a score and a sound effects soundtrack.
Also curious, given Hamm's dislike of the fantasy aspects of genre films, is the fact that the crux of the "twist" in Godsend is extremely loopy. What's happening with Adam makes little sense from a realistic/scientific standpoint, and how it happened just isn't possible. Of course, I'm not averse to fantasy, and I don't subtract points for elements in film that are wildly divergent from our beliefs and understanding of the actual world. But if Hamm is going to abandon realism when it comes to important plot points, why not abandon it wholesale, so that we can maybe see a film that deserves an A instead?
