I haven't seen the newest adaptation, and I haven't really had the desire to. Computer graphics is great and all, but if it's not going to look real, then I'd prefer that it not look ALMOST real. CG in movies like Shrek are great. Real life action is also great. But why have an Angelina Jolie that looks like a plastic doll of Angelina Jolie when you could just have her actually act in person and do CG effects around her (like 300 or other of the type). Also, it's been a while since I've read the original, but I thought Grendel's mom was pretty monstrous, definitely not a Lara Croft body type.
I do generally like the original work, action packed, full of good adventure. And I find it fascinating how boasting was almost it's own language and a badge of courage rather than just being annoying to all. Modesty was definitely not a virtue!
