The people who gave it high ratings must watch only 1 movie every 5 or 10 years. you cant tell its a chinese movie except for the chinese faces, everything else is a copy of something else or other already done in movies. copying parts of 10 great sci fi or thriller movies doesnt make it a great movie. the chinese movie industry has more money to spend then hollywood and still really cant turn anything decent to put on the screen. you're lucky if you find a good movie out of 10. the movie gets 5 stars because it is professional but that draws the line. theres also the requisite pop songs they like putting into movies...dont matter if pop songs dont belong in a thriller movie. they try to sell you everything at one time ...lol. again...a professionally done movie with decent actors but so underwhelming and a major copycat of multiple great movies. i love great thrillers and sci fis...sighhh...this had a little potential but sure wasnt it.
