Watched it for Skarsgard, but...
...meh.
I loved the 1984 Greystoke movie, and I'm fond of Skarsgard, so I was looking forward to this. But I was pretty underwhelmed. It was superficial. The legend of Tarzan has way too much going on to be crammed into a movie that's less than 2 hours long. It had about as much depth as the Disney cartoon, actually a bit less because the music in the Disney version plus the talking animals give it more heart.
Waltz was the best part, as is usually the case with whatever movie he's in. It's weird, he pretty much plays the exact same character in this, Water for Elephants, and Inglorious Basterds, but it works.
Samuel L. Jackson just seemed completely out of place and unnecessary.
Skarsgard was a vision, naturally, and I think he embodied the strong, silent, wild man type pretty well. He didn't have much to work with in terms of dialogue, etc, but he did fine. He has an understated acting style anyway, which I like.
Overall, glad I didn't buy it, but glad I watched it.
