Is Edward supposed to be that expressionless & emotionless?

I've read the first book long ago but it wasn't exactly the most memoriable piece of story I know so I don't recall much details.

And I just watched "New Moon" in hopes to get a laugh but much for my disappointment I found myself mostly annoyed for many things.

I don't know does the entirety of the main cast think the characters suck? B/c they're SO EMOTIONLESS in their performances!!!! Mostly anyway, like in lines that SHOULD have tons of passion/emotion in them or even at all. If someone spoke to me the way they mostly speak to/about each other certain lines, I'd have hard time even listening to, not to mention believing them. Alice the character was the most genuine in my eyes and ears.

Especially Edward seems to have only one or two facial expressions and he says almost everything in the same dry tone. Heck, even Kristen Stewarts performance compared to him was like fireworks and classical music all in one.

But yet, I think in Zarhura she was much more colourful and convincing and there was this trailer about RP's new movie wherein he was much more expresive and used more colourful tones. Though by no means would I call either of them great actors. But still. ARGH!!!
