One, we can seldom approximate the production values of Broadway/West End productions, which means having to consider scaled-down works for what they are, and not in useless comparison with their counterparts in other countries.
Two, we don't have extensive tryouts here, unlike abroad where shows are fine-tuned through weeks of out-of-town tryouts and previews before opening night. Here, the economy is much more severe: 2-3 months of rehearsal, 2-3 weekends of performances. Thus, I don't review preview performances, preferring instead to see the production when it has begun or settled into its groove during the run, to give it a better chance.
Three, whenever a production strikes me as bad, I make it a point to watch it again--because my negative reaction in the beginning might be attributable to outside factors like fatigue, unpreparedness, etc.
In short, I am willing to give productions a long leash to prove themselves. I try not to write reviews to feel clever about myself or to bitch and nitpick; I come from a place of friendship, incongruous as that may sound. I am passionate about Philippine theater, and I want it to succeed. Whatever criticism I direct its way is the tough talk of a friend.
But--given how small and self-contained the Philippine theater industry is, I also feel I can do a better job at reviewing theater when I am not part of it--not a practitioner, but more an informed outsider.
