Just watched this on Netflix last night, and I freaking loved it! I so hope it gets a sequel, because it ended on a cliffhanger.
If you liked the T.V. show Sliders, then you should LOVE this movie! It almost felt like a lost episode of Sliders. Alternate Earths, with different histories and doppelgangers of the characters. Only difference was how they moved between Earths, and of course who the characters were.
It just sucks it ended the way it did. You so wanted answers that you never got by the end. Who is their Dad? What was he doing? Who made the building? Where is it going? And why the hell did that crazy guy yell "He's lying!" before he got shot? UGH! Sequel better be coming!
You NEED to see this one, sci-fi fans.
