One of the Best Grade Z Movies Ever
25 May 2004 | by (Glen Cove, New York) – See all my reviews

Yes, I gave the film 10 out of 10. I'm not proud. Where this movie is concerned I have no shame. I loved this movie from the moment I saw it on New York's Creature Features way back in the late 1960's as a five year old.

At five this movie scared the crap out of me, now its just cheaply done fun. How can anyone who reads the title or the plot, about a research team on a lonely island being stalked by giant crabs that eat the brains of their victims and then can then talk like them, and expect it to be anything other than it is? If you're interested by interested the plot, then odds are you're going to like it.

What makes the film stand up as more than just a grade z piece of trash is the fact the actors sell what they are doing. You believe that that believe. Had this film been done now it would have been a nod and a wink and it all would have been forgotten ten minutes after the cameras finished rolling. The visual effects, the destruction of the island and the crabs themselves are a cut above the typical 1950's horror/sci-fi monster, there is something ominous about them, even if they don't movie all that well.

A great popcorn film.
