I have no idea what this thread is about, but nobody better be trash talkin' on "Primer" I'll go all "Zensteve said something bad about Avatar's momma; Crackerfunk explodes" on ya'll. That movie is a freaking essay in no budget cerebral sci-fi.
j/k Great movie though.
Anyway, we need that smiley where it pops in through a door, gets a freaked out expression and slowly backs away. I'm sure whatever I could say has been said, at least twice. Except this:

If you include the "Thanks" portion of the Puffy Chair credits, that's like twice as many people as on "Rome, Open City"
OG Mumblecore
Neo-Realism, Cinema Verite (different but similar). This isn't new territory. Actually that probably has been said - at least I hope so. Also sort of tangential. Admittedly Rossellini had quite a backdrop to work with - still.
CF:
I agree with you in essence about just doing it whatever your resources, but I come at it from a different direction I suppose. You really should check out some of the old school stuff though, I know you only like to see things in theaters, but with your love for this type of filming I think you'd really dig guys like De Sica, Visconti, some Rossellini.
Also Primary. See this anyway, just cause it's cool.

Stylistically influencing the whole "mumblecore" thing, arguably some level of influence on the dogma95 camp. Looking at that "thanks" list for Puffy Chair (imdb full cast and crew) makes me wonder how much of the notion of "one guy with a camera" is romanticized a bit for marketing buzz. (boom op, gaffer at the least on set) Obviously sparse resources and minimal budgets, but I'd bet there's as much (if not more) stylistic choice than limit resources involved.
