I thought it was decent, but incredibly unoriginal (and it didn't surprise me to see that it was produced by Paul W.S. Anderson, whose only good film, Event Horizon, was pretty much replayed here). Just about every idea that the film had was stolen from another, better sci-fi film, but i still found it fairly enjoyable for what it was.
I see that the recent 'Triangle' film with Melissa George is next Sundays SyFy film, maybe SyFy are finally spending their money on some decent films as opposed to that 'Mega Shark Vs Bad Acting & SFX' type "films".
