I love your website and am an avid follower, but I have to respectfully disagree with your grammar lesson. The present progressive is in no way less active than the simple present. They are both active tenses (as opposed to, for example, "the lawn is being cut by Tom"). You may still favor the simple present for its brevity, but it's inaccurate to favor it because it is more active. It isn't. It also has a different meaning. Although stylistically it may be better to use the simple present in screenwriting (which is not a medium that is renowned for its perfect grammar), it might be more accurate to use the present progressive to describe immediacy as opposed to the connotation of habitually mowing the lawn that "Tom cuts the lawn" suggests.
