Well, I'm not too keen on Zathura although my brother wants to go see it.
I loved Jamunji (saw it on TBS the other day, but I didn't get too see all of it, but saw most of it) and thought that was awsome, but I don't think I want to see Zathura because I'm afraid it will ruin Jamunji.
I also like the african jungle idea better than the outerspace/future idea.
