New Style in Cantonese Opera?

Recently saw 2 different Hong Kong 'mun moh sung' in Singapore. I found both of the artist have something in common - they do not 'hit' the beat of the drum anymore. What I meant is that they do not have the 'power' to accompany the last beat of the percussionist. Is this a new trend of Cantonese Opera performance? It looks so funny like they do not have 'strength'. The female artist I can accept the fact that she is not as strong as her counterpart but the male artist also gives me the same interpretation. Is it heading to the new type of trend?
