"The whole of season 1 of Academy is worse than Code of Honor" is a level of hyperbole that I find more than a bit hard to take seriously.
Honestly, conceptually there is nothing wrong with “Code of Honor”. It plays like a mediocre episode of TOS, overall.
A few tweaks in the execution and we might remember the episode in a different light.
And, not the whole season is worse, just a substantial portion of it.
