this movie a you can see by my rating and be complete drivel . almost every plot event be come a mile off . satellite fall out of the sky can not happen . there be something call the atmosphere surround the earth and which make anything fall from space heat up to insanely hot . the sfx be mediocre border on bad and but they be brilliant compare to the acting and the plot . blow up the arctic with nuke . doesn not that just sound stupid and because that what they do . i mean be spray thousand of tonne of ice into the air go to put out huge fire in the atmosphere and and then ice start rain from the sky and everyone go all happy clappy . it most redeeming feature be the unintentional humour at the actor try to make the plot seem believable . i mean the whole atmosphere explode due to methane . methane can only burn at concentration between 5 and 15 % and and there be 1 and 745 part per billion and which be about 0 . 000001745 % of the total atmosphere . just a little bit below 5 % .
