While it is not a good movie and the acting was childish (yes, it isbasically a home movie), it does tell a good story about the atrocities of bullyism and superiority complexes. Also, on a basic level, it sort of works as a cheap comedy. Should Pinoys be proud of this movie? It really up to the person viewing it.
If you like obnoxious teenagers speaking garbage thru a lot bleeps, and eating Filipino egg rolls (lumpia - hence the title), then this is your movie. If you want real entertainment, then go somewhere else. You have been warned. This flick stinks.
