Many clinkers, but what the m... There are so very many, many, many ways to pick this film apart for so many different reasons, most of them having to do with personal, scientific, technical, continuity, etc., reasons that it's become somewhat of a sport and rightfully so. The demands of the suspension of belief come at you so fast that it's near impossible to keep up with them. Artistic license is one thing, but still...
He asks her to gather some things so her and her son can come out to El Toro to stay with him because there is this incredibly huge, terrifying, alien spacecraft covering Los Angeles and yet, instead of waiting for the two of them to do do, he just leaves them behind? So while the whole of the greater LA area looks under the greatest threat EVER, he thinks it'll be just fine if she takes her son and goes to her regular shift as a stripper at some airport club, instead of going to the base? And BTW, El Toro MCAS was never out in the desert East of LA. It shut down because it became too closed in by LA's suburbs and the neighbors complained about the noise too much.
And this was a woman he wanted to marry so much that he bought her a ring. A ring he keep in his pocket until he knew he wasn't going to get into the astronaut program. Because, what the hell, if she'd said yes and NASA had too, I guess she'd have been screwed, so he had a back up plan anyway. And what was with Jimmy picking up and opening that box in the locker room and saying "This is a wedding ring." No, it's not. It looks nothing even close to a wedding ring. It looks sort of like a cocktail ring? Kind of. In a sort of cheap costume jewelry/gum ball machine sort of way.
Again, there are far, far too many places to pick at this film. Like where from the original showings did the illness of Russell Cates younger son go? In the first release he was throwing up by the side of the road because he was chronically/deathly ill and it was also talked about earlier. Also at Area 51 there was a deleted scene where Cates was demanding medical treatment for that son. Why was that cut after the first few times? I thought it was great and really humanized Cates, before the "heroic death " that redeems him. What idiot decided to cut that out? Though maybe they wanted him to be a pathetic clown instead? That's a shame. For those who have seen it you know it was better the first time. For those who haven't, you should try to find it. It's very small, but it really does add.
The the President's wife is dying from internal bleeding and she's not screaming in pain? Because if she's not then she's whacked out on such strong meds that she's dead to the world and ain't talkin' ta no one. And none of those dozens of MDs, including from that near flying OR on Air Force One, are even trying cutting into her to stop the bleeding? Bull! And where's the O2! No IV? Just a heart monitor that sounds really, really strong.
And it goes from one example to another to another to another, but no one ever watches these movies for them. Sigh. Oh well. It's still really, really fun to watch. So park your brain in neutral and keep repeating to yourself over and over again; "It's only a movie. It's only a movie. It's only a movie." You'll be just fine.
