It is a good piece of film. The actor and actress are of good quality. Great directorship and cinematography. But the script lacks something. Something more substantial enough to make it an excellent piece. It definitely moves me in certain parts by Cherrie and Koo's excellent acting skills despite Cherrie being a new comer.

For the first half, she reminds me of Rong Zu Er, but the more exaggerated version and it is not natural enough (Rong has done a better job). Later part, she moved me.

The whole script is like a mix-and-match sequence, slightly modified version from Romeo & Juliet and 50 First Dates.

Music was good.

If Louis Koo was on a mission to be the worst actor in Hong Kong, he could not have found a better picture to bring him such startling success. In this film, Koo tries to woo a Beijing theater student (Cherry Ying),but he suffers from memory loss, and he keeps forgetting who she is. A cute little CGI effect shows Louis Koo's face turning red from bottom to top like a thermometer before losing his memories. A bad choice of effect, really, since Koo is red-faced to begin with from his regular duels with tanning beds. This picture has nothing going for it. Cherrie Ying is forgettable, Louis Koo just plain bad. He desperately needs to stop making romantic comedies and restore what little remains of his credibility. If nothing else, WHY ME, SWEETIE? has left me longing for a mature romance that doesn't rely on cartoon gimmickry to hide its shallow insipidness. The search goes on. Meanwhile viewers who hanker for more tales revolving around fictional forms of amnesia can try the Drew Barrymore vehicle 50 FIRST DATES, which is at least more heartfelt than this production.
