I'll agree with Tacket
on the general rule here, without respect to which reviewer we're talking about - I've got no problems with anyone reviewing anything and expressing any opinion about it, good or bad. But there are several of what I consider Bad Suggestions bound and determined to come back around every couple of months where these independent films are concerned.
One is that there should be some kind of "award show" or award system devoted to fan and independent films.
Not interested, would not participate. And I view sending out the movies early to reviewers as being in the same category - ie, something that imitates "Hollywood" marketing and distribution but doesn't serve us for a variety of reasons. When I have something for public release, then I'll release it publicly, and then anyone and everyone is entitled and welcome to review and express their opinions of it.
