This was a little gem I watched on Youtube, which was apparently the pilot to a planned Canadian TV series that never happened.

A huge spaceship arrives through space and destroys an earth colony. The earthlings set off in an experimental spaceship to a planet deep in space to answer an encrypted message…

Ok, so its decidedly cheap and nasty with not much money being spent on production values, but the acting is first rate, the CGI is not bad and the story is very, very interesting.

At the time of writing you could still watch it here:
