I thought Ladykillers and O Brother were both decent but kind of tedious to get through. I love the Coens so I found both films were interesting in their flaws but not all too fun to watch

Well, ILD is now one of my favorite Coen Bros. I loved it, except
what happened to the poor cat on the highway.

I'd say Inside Llewellyn Davis but I'll know more after I start watching it in about an hour.

A serious man.
I think that movie just went above and beyond me.

I can't say that I've seen every single Coen brother movie. but of the ones I've seen.I have seen most of them.Ladykillers and True Grit.I'm my disappointment in True Grit was that it didn't seem like a Coenl brother movie. I was a big fan of the original one so I guess it was just a little disappointed.Ladykillers was just not that good of a movie.

Intolerable Cruelty was not very good.
Get me a bromide! And put some gin in it!

Definitely Burn After Reading. I didn't enjoy it. I wasn't a huge fan of Ladykillers and was a little disappointed with Big Lebowski.

Interesting.According to my IMDB rankings, it's a tie between 'Burn After Reading', 'Intolerable Cruelty', and 'The Ladykillers',(all rated at 7/10).
I think out of these three I would choose 'The Ladykillers', because it's the film I would least like to watch right now.
All these films came out over a six year period, but that doesn't really say anything meaningful, because their masterpiece 'No Country For Old Men' was also released at this time.

I dont think it can be considered any kind of "twist ending" in any traditional sense.

My least favorite, I guess would probably be either Ladykillers or Barton Fink. Lots of people like that one, but I thought the "twist ending" was pretty uninspired and didn't fit the rest of the movie.

So far, I've seen 7 of their movies. My least favorite is O Brother, Where Art Thou? I just couldn't get into it at all. I've only seen it once, however, and aside from Lebowski and True Grit, I've never truly loved a Coen picture the first time around.

I also don't dislike any of their films, but the one I rate lower would be Hudsucker Proxy.

You might be right.

Either A Serious Man or True Grit
"You must have a really wide foot, you got both of them"

From what I've seen of their movies, True Grit.
Don't get me wrong, it was good, but nowhere near as excellent as their other films. It drifted to being slightly dull at points and its sudden twist ending left me feeling depressed and empty.
The Big Lebowski's ending was sad too, but at least it was not flat out depressing.

If I'm not back in 5 minutes just wait longer.

I don't really dislike any of their movies, but The Ladykillers or The Hudsucker Proxy would be my pick if I had to go for one.

Didn't like Intolerable Cruelty all too much.
They've excelled in basically every other film.
Damn, they're great.

Only the opening scenes with geoff rush in Intolerable cruelty are worth watching.

I really didn't like Intolerable Cruelty.

I have enjoyed all of the Coen Brother's films (and absolutely LOVE several of them) but my least favorite would have to be No Country for Old Men.
It just didn't feel like a Coen film to me. I liked it well enough, but it's their only film I don't own.
And as several other people have mentioned, I'm going to praise Hudsucker Proxy and Intolerable Cruelty as two of their most often overlooked films. Both are hilarious (in completely different ways) in my opinion.
"I don't want Fop! I'm a Dapper Dan man!"

Intolerable cruely to me is just a step below their usual standard, and clooney just pissed me off to be honest.
It dosn't matter anyway we are all insignificant in this big ass nowhere, twilight zone s**t!

My Two Favorite:
The Lady's Killers
O Brother Where Art Though
My two least favorite:
'Burn After Reading'
'A serious Man'
I still do not understand what people don't like about The Lady Killers. That movie is AWESOME!
