Movie Reviews

DVDLaser - 7/10 by Douglas PrattAs Fifties monster movies go, the 1957 production isn't bad. There are a couple of good shock cuts, a special attention paid to idiosyncratic supporting players, and the usual mix of romance, military efficiency and doomed teenagers.
Creative Loafing - 6/10 by Matt BrunsonGiant mollusks as monsters? It sounds like perfect MST3K fodder, but the truth is that The Monster That Challenged the World is a fairly nifty '50s treat, with an intelligent script and decent effects (more so given its low budget).
Mark Leeper's Reviews - 4/10 by Mark R. LeeperThis 1957 film delivers a lot in the talk department and not so much in the logic department.
User Review - 10/10 by Paul EOne of the movies that turned me into a sci-fi nut at a very early age. The attack on (uncredited) Ralph Moody is a classic, and (also uncerdited) Milton Parsons is very funny as a cadaverous museum curator. One of the bestest!!!

User Review - 10/10 by Claire TThe best part was when they poked it's eye out.

User Review - 8/10 by Jonathan PQuite frankly of all the fifties monster movies I've watched this has been one of the ones that's had me engrossed the most! The creatures involved this time are water based demons that look like something you would have found in old school Dr. Who, I meant that as a compliment, they looked quite menacing! The story was good and there are a few frights to be had!
User Review - 8/10 by Gregory WDespite the misleading title (the monsters never really challenge much more than a single Naval base), this is actually a pretty fun '50s monster flick. It's worth the price of admission just to see the astoundingly copious amounts of something that they try to pass off as a sort of digestive fluid, but which looks really, really wrong on camera. Seriously, couldn't they have picked a better color than -white- for the globs of fluid the monsters tend to leave near their victims? Ah, the '50s truly were a more innocent time... But apart from the fact that the monsters seemed to be trying out for the next "Feast" movie, there's a lot to like here. The monsters actually look pretty impressive for the time, (not so much the mannequins they used for the dead bodies, but I digress), and the performances provide plenty of fodder for the MST3K crowd. If you have any love for the genre of '50s giant animal sci-fi movies, and you're tired of seeing iguanas with fins glued to their backs, check this one out. You'll be glad you did.
User Review - 8/10 by Josh CAs a sucker for 1950's monster flicks, of course I enjoyed this. This genre though is not for everyone, but for people who enjoy campy films, cheesy special effects, monsters who really aren't that scary (in this it is giant sea snails) then you will get as much joy out of this as I did.
