Surprisingly pervy for a PG movie
The baddie was a lingerie model, full buttcheek shots of her walking away too, after an attempted rape no less. Constant cleavage showing throughout.
Innuendo all over the place, like when J and K were switching seats. The porn theatre in the locker. The 'don't fall asleep' near the worm alien thing. The tongue in the ear scene. There were probably more pervy incidents I am forgetting.
Maybe I just got bored and started noticing this stuff more, but didn't notice it in the first and far superior film, except for some tame flirting in the morgue.
