I beef with CG is when CG becomes an excuse for a story.
Example: UltraViolet. Visually, it's stunning. I've seen folks bitching because "you can tell it's CG and it looks fake." They obviously didn't get the memo. It was an attempt to look like anime with live action. The colors, lighting and contrast wasn't supposed to look realistic.
Unfortunatly the acting is subpar and the plot is nearly non exsistant. They could have just 86ed the dialogue and played some good music and it would have been better.
For some reason Hollywood can't always seem to figure out what they should give the CG budgit too and what they should just completly pass over.
The result is some really intresting stories get F'ed up by bad CG and poor cinimtography and crap gets to look beautiful.
As for the actors. They're are some really good ones. Bale is one of my favorites and has been for a long time. Quite a few of them do a lot more then look pretty for the camera. Depp is one of my favorites, too. I'm not sure why disney just can't let go of wacky Depp dressed in insane costumes. Captain Jack was awesome. Now let it go.
You want to see character acting? Watch a few diffrent Depp movies. He doesn't play Johnny Depp in every movie. He becomes what the script requires. I'd recommend From Hell, Fear and Loathing in Las Vegus, Pirates of the Carribian and What's Eating Gilbert Grape (which also has another one who can act, Leonardo Decaprio).
Compare that to Keanue Reeves. Dudes been in some awesome movies that suited him very well, but that character is pretty much all he can do, ever. "Whoa"
