Query: Acting Kills Mediocre Movie

I don't expect special effects to be memorable in a low budget flick but this one was killed by the acting. Not one character in the whole movie was believable, endearing, intriguing, or even attractive. This went beyond facial features and expressions to actions -- running and chase scenes were like watching people in casts. Except they weren't in casts, except for that of the movie of course. Perhaps this could have been saved by a great plot, but the plot was weak and depended on good acting to create a sense of eerie tension. That failed completely as the main characters lumbered around like a couple of refugees from Weight Watchers. The only concern created in the viewer was whether they might accidentally run into a wall and knock it over.I don't usually bother reviewing a movie like this but I thought maybe you might find a warning useful.
