Yes, Charming does have certain charm, it's very beautiful as far as its design goes, and most of the jokes do work. All of the cast performs very professionally, but still. The plot doesn't advance naturally, it doesn't flow it stumbles ahead very predictably, as we all knew it would, to the not surprising end. On the road it hits every cliche in the book, many of them are mentioned as if jokingly, but they move the plot forward despite of making us all aware the scriptwriters know it's a cliche.
So basically, as I stated in the title, the end result is simplistic and forced. Can't say it was painful to watch, but I did cringe in my chair more than once, and its just plain shame, cause I can see here potential for a better movie.
