Did we really turn the lame “Jurassic World” into a billion dollar hit? Whoops! Like a one night stand you regret come sunrise, the reboot stomped all over the summer movie season despite its considerable dodginess. Luckily we can atone by firing up Netflix and watching at least the 1993 original, in which Steven Spielberg wows us with still sharp-looking dinos then flips that wonder on its head, terrorizing us with a relentless back half. The two sequels, also on Instant, aren’t as loved, and deservedly so. But they each have their pleasures. “The Lost World” is delightfully nasty, and “III” is trashy and witty — though not so much Sam Neill’s forehead-slapping raptor dream.
