Esoteric Happy Ending: Many have felt that the ending is this due to the sheer amount of Fridge Horror caused by the life Lucy is now living. note Example: She now has a young daughter whom she must meet for the first time every single day. What kind of effect will that have on the daughter over time?
Harsher in Hindsight: Rob Schneider delivers a pretty decent performance as a native Hawaiian, but it serves as painful foreshadowing for Schneider's later career, which consists almost entirely of playing increasingly-offensive ethnic characters in Sandler's subsequent films.
Heartwarming in Hindsight: Meta example. The ending of the film inspired a similar treatment program for real life patients with similar conditions, and it's found to have helped them greatly.
Henry's first recap video for Lucy claims that the Red Sox have won the World Series since her accident. This is followed by "Just kidding!" The movie came out in 2004, just a few months before the Red Sox won their first World Series of the 21st century ending the Bambino curse.
Barrymore's next movie, which she produced as well as acted in? Fever Pitch, set across the backdrop of the 2004 Red Sox season.
Narm: While Lucy's condition is not funny, what caused it... sort of is. "Stray Cow Causes Car Accident". Given the movie's a comedy and the fact this accident happens in Hawaii, while it's more than possible, it can be funny for some viewers.
Nightmare Fuel: The movie actually addresses the potential problems that Lucy will have the longer she goes with her memory being the way it is, specifically waking up and looking into the mirror to see someone ten years older, as mentioned by Henry. Their solution is that they are giving her a full life even though they know the wake-up point will be an issue every time. In the ending of the movie, she marries Henry and has to remind herself of their marriage, meaning she wakes up knowing she went to bed as a carefree girl and is now in a marriage with a stranger miles from home, though at least her father is with her at the end. Worse, they have a daughter, so unless they adopted or used a surrogate, she would have woken up pregnant for at least four months straight, with the only memories being those from before her accident.
They Wasted a Perfectly Good Plot: Many consider the premise itself (patient and her family dealing with short term memory loss and anterograde amnesia) having a potential for a very strong drama, yet being undermined by lowbrow humor typical for other Adam Sandler movies.
