Reptile is hardly original but that doesn't stop it from being a decent film.
Cut from the same dark cloth as so, so many, seedy underbelly US crime drama's, the plot behind this film is all too familiar.That said, its saved from mediocrity, by its adherence to the basic premise its built upon and plausible performances, from its cast.
Indeed the subdued, very conventional approach taken to character development reminded more me of Swedish or UK series, where the characters are ordinary people, with mostly, ordinary lives.
In summary, whilst Reptile isn't doing nothing new, its refreshingly down to earth approach to character development, does offer a little more to the viewer, than the conventional, "by the numbers", US crime drama.
