“In this crazy city, if you want to survive, you should be more drastic than it.” These are the lines from the latest trailer of Pang Ho-Cheung’s “Dream Home,” which will be on show 13 May timely following Pang’s romantic comedy “Love in a Puff.” I’m not sure if I am ready for a thriller which goes into deeper matters such as the imbalance of the local property market, but at least both trailers of “Dream Home”, and of course, the entire movie of “Love in a Puff”, were heartily filled with many of the director’s smart tricks.
