The Twilight Zone.

I cannot believe how amazing this series is. Sure, it has been made a parody of by hundred of other programs, but isn't imitation the greatest form of flattery? Anyway, I just got to say that this series lacks any and all special effects and usually a full cast. It is bare bones stuff; but the combination of great (admittedly sometimes cheesy) writing and old school acting (thanks to an era that didn't take into account only looks but actual skill) make it my favorite show of all time.

So yeah...watch it.

The best episodes I've come across so far has been A Pitch for the Angels and Escape Clause.

I recommend:

Time enough at last
The obsolete man
To serve man
It's a good life
Nothing in the dark
A stop at Willoughby

and of course...

Nightmare at 20,000 feet

(i'll probably think of more later)

I like the one with the twist ending.

So far my favorites have been Long Live Walter Jamison.
Everyone is the same everywhere.
Escape Clause.
The Hitchhiker
And,
A nice place to visit.
