It is difficult to articulate the sheer awfulness of DWELLER, but I will try.
The film opens with an outer-space starship battle. The cut-and-paste special effects would look obsolete in a 1980s video game. One vessel is struck by a laser, and plummets to Earth, somewhere in the woods near Ottawa, Washington. An astronomer, Trevor (Jeff Dylan Graham) decides to check it out, much to the chagrin of his boss, Ben (J.H. McBride). (Ben: "If you call me here again, you're fired." He is on a cell phone.)
The alien spacecraft is not easy to track down, but the alien therein has no problems tracking down unsuspecting victims in the woods. Soon, he/she/it claims a hiker and a videographer. The "special" effects in the death scenes are difficult to describe. The actors playing the alien's prey are made to loll around in the leaves while a graphic that vaguely resembles spermatozoa burning through a high-school film strip is superimposed over them. There are few things more horrifying than death by static cling in broad daylight.
Eventually, what passes for a plot is introduced. A trio of bank robbers has just pulled off a $100,000 heist, and they hightail it to the woods. They are not the brightest assortment of ne'er-do-wells, which the actors try in vain to play for laughs. There is much infighting and eye-rolling. Little do they know that death by rejected Weather Channel graphics awaits them, as well. There are even a couple of superfluous black-and-white dream sequences to keep things uninteresting.
It is rare to find that special cinematic turd with no redeemable features, but this dingleberry is hanging around as the second feature on the double-sided, two-disc set known as SLEAZY SLASHERS. It is the "b" side of PSYCHO SCARECROW. 'nuff said.
