Even though I enjoyed the other Spiderman movies (Toby McGuire and Andrew Garfield versions) with various degrees of enjoyment, this Spiderman version is no origin movie (since it's been done twice). It's more of a "teenage" Spiderman movie with an actor that is in his late teens.
The Dark Tower is Stephen King's magnum opus series. If you were to just take this movie "outside" of his books, it's mildly entertaining since it is only 1 1/2 hours long. Someone will do it justice (hopefully).
