Filth! Vile! Obtuse! Derivative! And the lead actress was drunk!
Pop culture gaming kindly showed me the company that makes coat-tail riders like "30,000 leagues under the sea" and "I am Omega." I noticed these on the shelves of Blockbuster from time to time, wondering just how bad they really are. For some reason, the company's blogger had the gall to complain about the vicious reviews their films receive: http://www.theasylum.cc/blog/2010/01/worst-movie-ever/#comments
I couldn't resist a (hopefully) rational response tending toward neutrality. I did my level best to keep digs to a minimum. However, it is 'awaiting moderation' which suggests it will never reach more than the mod's eyes unless I reproduce it here.
It is fair to criticize the hyperbolic vitriol that your films attract.
However, your business model relies on consumer inattention somewhat. The new owner or renter of "The Day the Earth Stopped" will overreact when his or her expectations are ground into dust. The backlash resembles the trope where a lover learns she or he has been lied to and suddenly "everything you ever told me is a lie!".
Another factor is the potentially sheltered film pallete of today's audiences. With access to one hundred years of film history via netflix, youtube, ect I can only watch the 'best' and 'critically acclaimed' content for a good long while, perhaps several years. This would give me an unrealistic standard about what constitutes an average movie. In the past, there were three tv channels and more theaters showing B movies. Previous generations dipped their hands in a greater spectrum of quality than your likely critics. So, when a film of lower production values starts rolling, they subjectively sense a much greater disparity than actually exists.
I admit I haven't watched any of your films, but I suspect they are average - despite their coat-tail riding impetus - rather than horrible. Instead, I had the dubious pleasure of watching "The Zodiac" (2006) instead of "Zodiac" (2007) by one of your competitors. After the initial confusion and disappointment at having selected incorrectly, I watched on. There are more entertaining ways to spend two hours, but it could have been much worse (in terms of actor dynamics or narrative coherence). Probably, Asylum's offerings share the stigmata of Compromise (with the budget).
Obviously, your choice for worst movie [Crash] is clearly limited to 'mainstream' productions. It practically shone in comparison to drek like The Garbage Pail Kids and most of the victims of Mystery Science Theater. None of those are the very worst though. Be glad you will never see the foolish, incomprehensible student film that my sister starred in. I have made it my mission to destroy all sixteen copies. I checked just now and he published my comment.
