*spoiler alert*
If you're looking for a time travel movie that has many plot holes and make no sense at all, then this is the movie for you. Let's send untrained people into the future to fight alien version of Mr. Bigglesworth with tenticles . It would take 10 minutes to brief people about the rabid "Dog"tor Octopus, but instead they take their chances with untrained civilians. What I don't understand, is how 30 into the future we have no scientific knowledge about the aliens. They come back to the future and ask a kid in high school when a volcano errupts. The daughter was supposed to have a PhD and couldn't figure it out!? What about the weapons? What were they doing for 30 years? Oh putting the time machine together with bubblegum and paper clips. The ending, even more of a disappointment...wish I could travel back in time to get two hours of my life back.
