This is a disaster B-Movie, its title is "Airplane Vs. Volcano"... yet looking at the reviews here, it would seem some people were expecting a blockbuster of multi-Oscar winning potential and a stella intellectual delight.
Those people are idiots who expect too much.
The acting is everything you would expect from one of these movies, the effects and plot follow suit.
The purpose of this movie is to allow your brain 90 minutes of rest, in that this movie succeeds.
Just sit back and enjoy the ride, let a laugh escape as you gaze in disbelief at some of the huge leaps it takes with logic.
But overall if you're a fan of these films you know what to expect and will enjoy it, for everyone else who just came here because of the flashy poster, amusing title, perhaps you just have a love for Dean Cain, or maybe you're just curious how a plane can take on a volcano? Whichever is your reason, this movie will serve its purpose for you, there are much worse movies of this genre out there (Titanic II, or Snow Sharks for example), at least this one avoids the teen frat boys at a drunken party feel.
In the immortal words of Bruce Lee in "Enter The Dragon"... "Don't think.... Feel" and you will have a fun 90 minutes. otherwise you can just sit there mocking and feeling offended that someone could release a movie of this style like so many of the other (clearly snooty) reviewers
