These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

YMMV: Freeman's Mind
Alternate Character Interpretation: Gordon Freeman's just plain bonkers here. Among other things, he spends a lot of time looking for drugs and fantasizing about murdering his coworkers.
He's degenerated to Designated Hero/Villain Protagonist by part 21 at the very latest, discussing his plans to climb the corporate ladder by kidnapping an executive's wife and framing his superiors.
Broken Base: Episode 47 gets hit hard with this. It's during this particular episode that Ross Scott allowed a friend of his to play around with sound effects from other games and such, and implement them into this episode. Such changes being the different gunfire sounds for Freeman's weapons, headcrab voices taken from Half-Life 2, and even much more realistic explosion sounds for tank fire. While some found these sound tweaks to be decent, others found it distracting, and out-of-place, after having watched the series through stock sounds for 46 episodes. Afterwards, Ross chose to just go back to stock sound completely, but episode 47 ends up leaving the new sound-effects intact; now making it seem even more out-of-place if the viewer feels distracted by the one-off sound tweaks.
Crazy Awesome: Gordon. Scott said that he went for a mentally unhinged and quirky characterization because he couldn't see a normal person surviving the events of Half-Life. His more eccentric attributes do indeed save his life a few times. In later episodes, he also gets pretty lax with his personal safety, seeing as how he considers running right past a Bradley through an open killing field while it attempts to hit him with its autocannon to be a completely viable strategy.
Gordon: Alvin York killed dozens of people, and he was a hero! He didn't even want to, he was like me! Am I a hero? Eh, I don't know, I don't think it's very heroic if the only person you've managed to save is yourself.
Ensemble Darkhorse: The series as a whole is this in Ross' works. Ross Scott used to only create Civil Protection, but it took a long time to make new episodes, mostly due to the time it took to animate everything. So he created Episode 1 of Freeman's Mind as essentially a comedy skit/experiment to give his fans some entertainment in between episodes. After he created the second episode during another lull between Civil Protection episodes, he planned to end it right there, but fans really loved it and demanded more, and now it's one of the most popular machinimas around.
Fridge Logic: Invoked at several points, with Gordon wondering about the state of the rest of the facilities (and why the place is so recklessly dangerous), such as one time if he wondered if janitors had a higher survival rate since they both have rudimentary melee weapons, knowing the layout of the buildings, and had keys to everywhere.
Hilarious in Hindsight: At one point, a dying guard tells Freeman that a tram leads to the surface. Freeman muses over it, saying that so far the guard had spoken in annoying half-truths. He follows the tram-track, and it does indeed lead to the surface.. But not out of Black Mesa.
Freeman constantly lamenting his lack of a grappling hook becomes funnier if you've played Half-Life: Opposing Force, where Adrian indeed gets a grappling hook...that's just a Barnacle that was pulled off the ceiling, and that he'd probably just pass up, anyway.
