I have movies that the story is pretty cookie cutter but the dialog and action and actors make it a fun movie to watch and I've seen movies with great actors and action but the story and execution just didn't make it worth watching again. It is rare to find a story that doesn't have problems in it but the one problem I think that happens is when the feel of the movie focuses hard on a story that has the "glaring story problem" that detracts from the movie. If the story itself it forefront and the acting and characters are tagging along for the ride so to speak then a bad or poorly executed story can make a movie a clunker. If the movie focuses well on the characters and interaction/development of them and also has interesting action to entertain then a flawed story can be somewhat ignored for the fun involved watching what happens next. A lot of sci-fi movies end up based on ideas that the logic is wrong but you can ignore that and enjoy it anyway.
Hey Lynx, you're spot on and I couldn't have said it better.
