I'm thinking about a call to Trading Standards on this one as its not as the title would lead you to believe. Out of 10 films 4 are disaster films the rest most definately are not.
Earthquake, Avalanche, Absolute Zero and Ultimate Limit are the only ones in this collection I would class as true disaster films.
Flight 747 - is a mid air robbery on a cargo plane - no crash no disaster more of a thriller
Volcano - well there is one at the start but the film is not as descibed on the cover, its more about a man who has lost his wife in a volcano and spends the rest of the film tracking her past - I got bored half way through and switched off.
Tornado - totally weird - more a spiritual mystery thriller but no way a disaster film, its worth a watch just to see how weird it is!
Epicenter, Disaster and Fire I've yet to watch but judging by the synopsis of each of these films they are no where near disasters either so in short apart from the 4 films which for the price isn't bad be prepared for a disappointment.
