Great technical elements.
Terrible, flat characters.

Titanic was a farce : For all the relevance of the actual story of what happened, that film may as well have been shot in the Empire State Building, and called "Empire"...not to mention he actually slandered the petty officer, by having the character fire a gun into the passengers : Something that NEVER happened in the real story. Seems Cameron, Bay (Pearl Harbor) and Mel Gibson all studied history in the same school :-\

...proper education leads to proper values of life and perspective on things. When that fails, we get socially accepting... then, its all lost. This is why people cosplaying as WoW characters would be deemed clowns or lunatics a few 5 decades or so ago, and not 'its normal'...just like furry people, and all the human examples of idiocy.
People having a hobby that they like and even, that can help them socially or economicaly, thats all fine. Heck, if you want to paint yourself blue, well whatever. But to start making that your lifestyle, or emotionaly attaching yourselves on stuff like music bands, TV series, movies, GAMES, etc, that is really, REALLY retarded. Fans, ok. Fanaticism, go into a desert and stay there...
Ahh...the wonders of human social disintegration. And then people wonder why we all care less and less about each other...i wonder why....
...and yes, Cameron isn't doing anyone a favor by making movies (i lie, the studios thank him. i'm sure). Crappy flashy movies with as much substance as an army panflet are hardly worth the bother to see the trailer... then again...human standarts have been steadily dropping since last century...

Ding ding ding!
We have a winner.

I feel depressed after watching it cause it sucks.

I loved it, but I get those who hate it. I see their points as valid, but they don't diminish the movie as much for me. I'll admit, I've been having dreams where I'm a blue cat person and doing some of that neat stuff from the movie, but I am not a furry, I am not depressed that I'm a human and I'm not upset with our planet. I like it fine, thank you very much. It's just like one of those dreams where you're James Bond and you're doing that bungee jump into that dam, just the little boy inside of me jumping up and down at something crazy and awesome.
Also, I am not surprised by people getting addicted and depressed about that world, because even though I have faith in humanity, I am also a realist, and I know that some humans are just messed up like that. You look in the 80s, with the odd case of the people killing themselves because they get too engrossed into the world of Dungeons and Dragons, and it's very similar. Of course, the majority of D & D players would never lose touch with reality like that, but a microscopic part of our population obsess over "second lives" (many of them use Second Life).
If anyone has these sorts of feelings, they need a psychiatrist ASAP, because there's something deeper in their minds that causes this reaction, and doctors can help them overcome it.

Every once in a while, I almost felt like I had somehow tricked everyone in the theater into watching a video game cutscene. It didn't feel good.

"Aliens" isn't technically a good film : It's full of clichés and the like, but it works. It works well enough that it was the first ever sci-fi/action film to get the lead actress an oscar nomination.
Oh how the mighty have fallen.

You seem to be forgetting Homo erectus, Homo ergaster, Homo heidelbergensis, and Homo neanderthalensis (and probably a few more that I'm forgetting as well).

i sort of get this. i mean, the way they are presenting it "depressed because pandora is an intangible place" is pretty pathetic and stupid sounding. but i remember being incredibly bored with the real world while pandora was still fresh in my mind. while watching the movie EVERYTHING was very new and incredible and vibrant, and when i took off the glasses i had a very distinct feeling that the real world was just bland and monotonous. of course, that only lasted and hour or two.

That's an interesting syndrome. Not that being depressed is any fun, but I would like to experience something like that.

After watching Metalocalypse, I want to go to Mordhaus & become a klokateer because metal and violence appeal to me

The blue people don't look any more realistic than Gollum from LotR or King Kong. I don't see what all the hubbub is about.
It really doesn't look that visually appealing to me.

I second the appealing.

Nah, just violence for me, that's all.
