I'm sure this film will increase guinea pig sales, and as a byproduct dumps and rescues. Are the filmmakers to be at fault. No. Are the moviegoers to be at fault. No. Adults who cave into there kids desires without doing the proper research are at fault.
If you want to really help don't protest against the film. You will just come off as some zealot. Try harder to educate people you come in contact with about the realities of
GP care. Also since the rescues will be overloaded consider working with them and fostering some of the overflow until the surge passes.
