When at the beginning I saw the 'Reality' footage added in, I thought immediately that I was NOT going to like this (I HATE 'Reality Shows' and most 'Found Footage' films) But, I must say, that it was actually used very judiciously throughout the movie.
I don't usually care for Dallas Roberts that much either, but I must admit that he did a decent job in his role. Every time I see the guy, I get this eerie feeling that John Ritter has been resurrected! DAMN! Also, as you actually get to see the real people here involved in the 'True' case, it does have a sneaky way of drawing you into the film.
With such a simple concept, the way it was done was decent and moderately effective. When I saw the REAL guy I truly felt quite sorry for him, especially when they show the credits at the end (not to give anything away) I really just felt bad for him.
I think the thing that I appreciated most was that the way it was put together and the way it was put across, you never get the feeling that the film makers are exploiting the idea like so many other 'True' stories. Especially with the footage of the real guy, you get a strong sense that they are honestly trying to portray events as they actually 'happened'.
A surprisingly interesting and mildly effective film that somewhat surpassed my earlier expectations...
