I've been inspired by this recent release of Skyline. I don't plan on seeing it, not only because of the disappointing reviews but also my current philosophy of avoiding the movie theatres like the plague because Hollywood doesn't deserve my money. I digress.
Skyline is the perfect example of SF glamorized only for the FX then roasted for total lack of meaning. A cheap thrill, an insult to the human mind. But I say we still need movies like it to come out, even in our modern era. It will only fulfill the generations of humorously horrible movies. I would make the connection that such bad, CGI imbued movies are akin to such laugh-fests as Attack of the Killer Shrews or The Giant Gila Monster. In a sense, they are important for the SF genre only so future fans have the ability to enjoy themselves and laugh at the horrendous low-points of SF. So don't be fearing that SF has lost its glory, in fact horrendous flicks are just planting the seeds for future geeks to enjoy.
