Hoi sum gwai gau hoi sum gwai

This is the fourth installment in the series in which the attention slips away from the classroom to ghosts and Kwai's (Raymond Wong) relationship with Annie (the pretty Pauline Yeung). Annie's cousin (Charlie Tso) is also vying for Annie's affections and Kwai is constantly looking foolish in front of him. Eventually, the cousin tries to have Kwai killed by the Happy Ghost (also Raymond Wong) helps him. Also, a boy band of four named Beyond (think New Kids On The Block or the Jonas Brothers, with four people) are students here, probably to make this a teen date flick. The girls, including Fennie Yuen and Loletta Lee, are barely in this film. Things happen, some of it amusing, but I would guess at the time this film was at least partially made with an eye towards elevating the group Beyond. If you've watched the first three Happy Ghost films, watch this. It has its moments and its not boring. The special effects are pretty good. Not essential otherwise, but it passes the time.
