This is a strange film in which man travels an enormous distance to see if his father is still alive, killing a spaceship's crew on the way, only to find his father has lived on apparently nothing for years but has suddenly decided to kill himself.
Yes, it's disjointed and rather unsatisfying..
This is a very special kind of film, the sort that used to be called a TV movie.
The use of TV News broadcasts to move the story on, the B Grade acting, the holes in the plot all make a classic American TV movie that you might happen upon at midnight, watch for 5 minutes and fall asleep.
Unfortunately it is now deemed good enough for cinemas and features a full catalogue of explosions culminating in the demolition of an entire hospital and all apparently based around trying to spoil a secret service agent's reputation. An attempt to kill the president manages to kill 28 agents, blow up approximately 12 vehicles and half a National Park, but they forgot to target the guy himself and thus he swims off.
