riotously cheesy lunacy about lava spew from the la brea tar pit in los angeles . even if you attempt to suspend disbelief by ignore this ludicrous premise and you will still be howl with laughter at the inane dialog and nonsensical plot contrivance and and wildly reckless scientific plot hole that parade across the screen . i have a theory represent every successful actor be doom to appear in at least one bad movie at some point in his or her career . this be tommy lee jones turn . although he make a decent effort and the script be just so pathetic even he go down in flame ( oops and sorry about that ) . most of the support cast be also choke by the hackneyed writing while a few of the actor simply phone in their role . anne heche deserve special hall of shame recognition for her awkward portrayal of a scientist . she be about a convincing in this role a pee wee herman and and even he would have at least do a well acting job . since the scientific plot hole be too numerous to list here and i would instead suggest that you screen the film with friend and and have a game of find the scientific absurdity . the loser could be force to listen to tape of corny line from the movie like everybody look the same over and over . here a sample of the kind of nonsense you can expect represent a scheme to blow up a building be devise and engineer and and the dynamite set and detonate all within a space of about 20 minute . let u not forget the obligatory disaster movie clichés represent divorce dad and scientist who get ignore by everybody and obnoxious cop and tough street kid and bratty teenager and greedy investor etc . while all be present and in abundance . the film also bash you over the head with a relentless barrage of political correctness . for fan of cheese and silliness only . all other viewer represent beware .
