The main storyline with Chakotay is ripped off straight from 2001: A Space Odyssey and is semi-interesting for it's exploration of Chakotay's past.

The most interesting aspect of the episode is, however, the Doctor. He decided to give himself a holographic flu after being accused of insensitivity by Kes. He wants to prove his point that being sick isn't a hindrance to carrying out his duties and like him, the rest of the crew shouldn't be "coddled". However, things don't do exactly as planned and he learns a lesson of sorts.
