Why the wave ending had to be cut
So in the theatrical version, the oil rig guys are nice to the aliens, bud goes down a huge hole to save them, they find him and as a thank you they take him and the rest of the crew back up to the surface. Pretty simple.
In the director's cut, the oil rig guys are nice to the aliens, bud goes down a big hole to save them. They find him lying down and bring him aboard and save him. Then they tell him him that they like to watch TV, have formed a wretched opinion of mankind based on TV, and have decided to kill everyone with a series of waves. But at the last minute they change their minds because Bud showed them that man can love too? Sounds to me like a strech. It takes about 30 seconds for them to reverse course because of a couple of dopey text messages?
