In reality, because of the short length available for aircraft to land on carriers, there are a set of arresting wires on the deck which are supposed to be caught by a tail hook mounted on the plane.
Carriers typically have 4 wires, and a landing is usually considered a good landing if the pilot catches the third wire. Repeatedly failing to catch that third wire can result in a pilot losing their carrier flight qualification.
If a pilot catches the first wire, he's landing short of the optimal "safe" zone.
I've not seen the movie.
As has been pointed out, Best is the hero of the movie rather than a potential washout. I've also read that the script of the movie is considered cartoony and clichéd. So, it is likely that in the context of the movie itself "first wire" is the best wire, and despite the fact that Best is gliding his plane in, he will still stick a perfect landing.
