i think that it be almost a if they have start on a movie and then midway decide to change the plot . the idea be great but it do look like the script be struggle to convey the idea of time travel . i think that they should have stick with the satellite part ( and make it more convincing ) . as far a the acting be concern and some be good and some be terrible . i think that denzel washington be do more posing than act and a if he think that he be audition for 24 or zoolander . you also get the feeling that it be design to be part of a sequel franchise . the best thing about it be the special effect .
