When Emma, Seiji, and Lamar are interrogated, Baxter describes Emma as "a woman whose career is all washed-up." That's a pun on Debbie Gibson's music career, which reached its peak with the album Electric Youth in 1989, but floundered through the 1990s. See more »

Only More Monster Footage Could Save a "Movie" This Horrible
24 June 2009 | by (Bothell, Washington, Land of Rain) – See all my reviews

This is one incredibly bad direct to video monster flick (though "bad direct to video monster flick" is probably a redundant term). It has all the classic earmark of the worst DTV has to offer--horrible screenplay, idiotic dialog, lots of talking in lieu of action, that incredibly annoying "avid fart" digital editing, bad grade z cast, Ed Wood level acting and directing, and GC effects that any grade schooler would almost be proud of. Now, this piece of S could have been entertaining despite the abundance of retarded MST3K-worthy acting, writing and direction if ONLY they had sprung for more than five minutes of footage featuring the title monsters. Imagine if King Kong V Godzilla had only featured the title monsters in short three to five second blips and the all out battle between them takes all of eleven seconds from start to finish. Now double how much that would suck and that would be the equivalent of this "film."

To sum up--and incredibly bad, incredibly amateur hunk of junk that would be moronically entertaining if it just weren't so damned boring.
