I watched this film on cable whilst on holiday, and immediately regretted spending a valuable 90 minutes of holiday time on it. The plot was a rehash of every disaster movie ever made
1. Nuke lost & blown up 2. Passenger ship caught in the tidal wave 3. Secret passengers & spies on board 4. Rescue begins whilst being hampered by secret passengers & spies 5. Etc. etc.
Terrible acting, thin plots, truly dreadful special effect. My recommendation would be to spend that 90 mins catching up with old friends, mowing the lawn, washing the car, cleaning the fluff from your belly button - anything except watching this film.
