The 3 most obscure of Rander's collection for me are:
Pusher
Secretary
Super Size Me

The most mainstream:
Terminator 2 (Judgement Day)
Independence Day
The Day After Tomorrow

The most overrated:
Terminator 3
Independence Day
Saturday Night Fever

EDIT: Sorry, got the premise wrong, that it had to the movies from the poster above me. Changed that now

3 - Obscure

Dust Devil
Wizards

Obscure indeed, I don't even own these. 

It seems many people did not bother to read the first post...

I agree.

Most Obscure
La Momia Azteca Contra El Robot Humano
The Rape of the Vampire
Ölüler Konusmazki / Aska Susayanlar Seks Ve Cinayet

Most Mainstream
Spider-Man
Superman
The Manchurian Candidate

Most overrated (this part was really hard*)
Natural Born Killers
St. Elmo's Fire
Platoon

* I mean, you don't own many highly rated films to begin with (which is good, actually) and those yu own I like myself...

In the interests of keeping the thread going (and getting another opinion on my collection)

For goblinsdoitall
A challenging collection, not just because of the non-English titles, but also some blank profiles
3 Most Obscure
Fear and Loathing in Las Vegas (was it just me, or was the plot for this rather flimsy?)
Jabberwocky
Wolfsheim (any info on this?)

3 Most Mainstream
E.T.
Harry Potter und der Stein der Weisen [Sorcerer's/Philosopher's Stone]
Fluch der Karibik [Pirates of the Caribbean] (great mainstream fun)

3 Most overrated
American History X (I kept feeling like it was trying to be a US Romper Stomper and also trying to hard to be 'hard')
Der Pate [The Godfather] (I can't see why this is considered 'brilliant' and not just good)
Reservoir Dogs (Clever, but not unique.  Imho, not the great piece of work the fanboys claim)

**Glad to see In China essen sie Hunde in your collection.  It's one of my favourite movies!**

For ya_shin
3 Most Obscure
Clockwise (I didn't even know that this had a legit release)
The Fearless Vampire Killers or: Pardon Me, But Your Teeth Are in My Neck
Nick Frost's Danger 50,000 volts

3 Most Mainstream
The Matrix (still love it)
The Simpsons (and the creators know it, embrace it, love it!)
Ocean's Eleven

3 Most overrated
Ghost in the Shell 2: Innocence (pretentious.  Although visually great, not great in itself.  Toppled Akira out of this list)
The Adventures of Priscilla, Queen of the Desert (I'm sick of every time "Aussie cinema" is talked about in the media, this and The Castle are considered great)
King Kong (2005) (It's a gorilla, not a human, so don't give it human emotions!  1933 for me please).

I must say, a varied collection.  I struggled to get the mainstream list finalised.
Glad to see Black Mask making TWO appearances in your collection.  Check out the remastered version, it's gorgeous!
I left 2001: A Space Odyssey alone, because it's already been picked on.  Amélie from Montmartre survived because I spotted it too late.

Same here, 19933 all the way (yes, I know I own 2005 twice...).

Don't tell me that we will have another remake of this in 17926 years 

Are you a relative of this guy?

Sorry Ya_shin, too tough to resist 

P.S : for the next user don't review my collection. This the turn of W0m6at not mine

from W0m6at's collection:

3 Most Obscure
TISM - The White Album - I remember crowd surfing at one of their gigs in Adelaide years ago
Red Dwarf - Well known by some, understood by few, completely lost on the most
Machinist - very strange movie, but great
Death to Smoochy - hilarious little movie!
Flash Gordon - For it's time some great effects, and some of the worst

.. I know a little beyond 3, but all worth mentioning

3 Most Mainstream
Interview with the Vampire
Pirates of the Caribbean - is there anyone that doesn't have this in their collection?
The Matrix - ditto to the above, although Matrix 2 was still good, I think the final one lost something
... and ... It's a wonderful life - simply because it appears in so many other movies!

3 Most overrated
Ali G In Da House - after a while, his jokes are all the same
12 Monkeys - Interesting, but not as great as everyone says
Chronicles of Riddick - Pitch Black - too bad the lights weren't out for longer

3 Most underrated
Butterfly Effect - great movie, very surprising
Memento - left the movies with a major headache after seeing this, and still interesting to watch
Batman Returns - Probably the best of all the batman movies, kept the true darkness of batman

Fairly varied little collection, noticed that Black Mask made 3 appearances in there!

Cheers
Tom

Does someone want to get us back on track by rating TommyG's collection?

btw Tommy, it's Albun, not Album.  It is the lads from TISM after all!
