"The Deep End" was made as "Reckless Moment" over 50 years ago with Joan Bennett and James Mason in the starring roles. This older version was a more involving (and believable) film. The current movie might have made more of an impression if it had been filmed in black & white, like the original. In "Reckless Moment" it was a teenage daughter involved with an older man. Having not read the novel which is the source for both, cannot comment on which is closer to the original story.
