Everyone should watch it.
Especially devout Scientific Methodists.

So anyway --

Walter's Team
Walter: INTJ
Walter's son: ISTP
Astrid: ISFJ
Olivia: ISTJ

Not Walter's Team
That tall black guy: INTJ
The woman running Massive Dynamic: ENTJ
That guy who Olivia always talks to: ESTP

I don't remember anyone else.
Also, I'm like Walter and I can't hardly remember anyone's name.
