Big Budget Films and Perception

Some films are once and done. Some dramas, difficult biopics, whatever the case may be (I'm thinking something like Syriana but don't necessarily mean to pick on that). Others get people coming back to catch things they missed or simply because they enjoyed the experience so much the first time, they couldn't resist. A great example would be any Star Wars movies. When people dislike them, they still revisit 3+ times. And yet some would call the prequels failures.
