Sneakers came out in 1992 and in 1999, EFF and distributed.net brute-forced a DES key in under 24 hours. If that's what a bunch of randoms could do in 1999 with commodity hardware, the NSA almost certainly had ASIC, FPGA, or supercomputer based tools to provide nearly the same functionality much, much earlier.
If you pay attention to the talk around The Box - the concept is that the mathematician found a "shortcut" through western encryption algorithms. That's a very accurate representation of plenty of crypto attacks. For example, a bunch of WiFi attacks are nearly as magical as The Box.
The film eventually reveals that it's the NSA that wants the box...to spy on other government agencies. Also rooted in truth; the NSA created DES with intentional weaknesses, mandated its use for the government and pushed its use in private sector.
I think you have a serious misunderstanding of the DES story: the NSA made changes to the S-box without explanation in the 1970's, and everyone was suspicious at the time, but then 15 years later two researchers "discovered" differential cryptanalysis, and realized that the changes the NSA made actually protected it against this form of attack. So instead of weakening it, the changes the NSA made protected it against a then unknown (in UNCLASS) attacks.
The NSA did push to reduce the key size from 64 to 48, which is why the eventual standard was to the always bizarre 56 bits.

Sneakers automatically decrypting something is a conceit of the movie to show what the device can do (find primes to break encryption), even if the way they go about showing it is silly. If you had more time and an understanding audience, you could replace that with a scene where they try out the encryption breaking on files, etc, and the movie works the same for the most part if you explain why it's important. It's all understood technology, explained with the limitations of the time.
Wargames rests on an AI which we still can't make and aren't sure how to make or if it's necessarily possible to make. The movie falls apart entirely if it's not a learning computer. The conversing audibly is a conceit to make it more approachable as a film like in Sneakers, but that's not the largely problematic part.
