The acting was wooden and the dialogue annoyed me. The science was cool and plot was catchy but the delivery was boring. Some of the dialogue was so vague it left me asking why didn't they explain more there.....why wasn't there more conversation? The part where they made love for no reason whatsoever and all she says is we're suppose to.......what? There was many scenes where more conversation between the two actors would of made for a more complete story. The movie was forgettable and didn't leave me questioning our existing on this planet........it left me questioning why I sat through the whole thing. The potential was there........ disappointed in it.
