It certainly seems that way.

: Why does it seem like everyone is making decisions with an under developed
: frontal lobe?

S-IV side effects? But that doesn't explain everyone else.

: In regards to the ending: is it just me, or could we have avoided this whole
: mess if there were fewer people acting like idiots?

Like if one person had bothered to find out WHAT Halsey was talking to 'Mdama about, or WHY?

: Has the UNSC gotten really slack with radio discipline?

Yes.

: Why does Palmer constantly hate on "egg-heads" when she owes her
: entire existence to them?

I guess they thought it was funny? It did seem to me like her usage of that particular word got toned down after a while, so perhaps 343i realized it wasn't funny. I still don't really like her, eggheads or no eggheads. And that's too bad, because when I found out Jennifer Hale was doing her voice I wanted to like the character - but she's completely off-putting.

: I think what makes this series really difficult to enjoy for me is the fact
: that everyone keeps arguing and no one seems to be making intelligent
: dialogue. Sure, there were a lot of cool moments and overall I enjoyed the
: gameplay, but I just can't take the story seriously when I'm constantly
: being frustrated by it.

Thankfully for me, I enjoyed it despite these things. Probably to do with playing it as part of Kermit's co-op night. That being said, it could benefit from some stronger writing. My hope is that if there's another season they will sit down and plan out a more compelling story and more likeable characters ahead of time.

: And Palmer. Honestly, did a nerd steal her chocolate bar when she was a kid
: or something? The worst part about her attitude is that it reflects onto
: her subordinates so when this other guy (forgot his name) is in charge of
: the operation, he's constantly making fun of me for being dumb (he's the
: guy who says things like "This is a tough one; you have to push... a
: BUTTON!"). Seriously, Palmer is a bad leader and she should feel bad.

Yeah, she might be ok as a lone wolf operative but it's difficult to imagine anyone being stupid enough to put her in command.

: Anyway, sorry for the rant. Back to my corner.
