Big Sky as a title makes the viewer anticipate quite an adventure, but Ryan Philllipe has not done much that is noteworthy lately, he reached a peak of sorts as Bobby Lee Swagger in the forgettable 'Shooter' a show which finished its run like a conclusion to an extended contract.
Any suspense drama about kidnapping really needs a good character actor in the main role, someone like Bill Pullman for example, who did a great acting job in the Sinner, it also needs to have a good support cast with some experience with this genre, but when the main female cast all look suitably photogenic, nubile and pout a lot you know you are in for something formulaic with a suitably open ended story to guarantee the chance of a five season run, especially if its from David E. Kelley, well known for high end American soap operas like L.A. Law, Chicago Hope, Alley McBeal; David E. Kelley has quite a list of successful shows, whether Big Sky will become one of them we shall wait and see.
