^^^Look at the number of people involved in producing the script. Every plot becomes an unfinished subplot, even the interesting ones, like Loki/Odin. For me, this is why the sequel simply is not as good as the original. The sequel is not really written. (I gather that things like this happen because the director is mistakenly regarded as the primary creator, so he's allowed to interfere at the wrong stage.) I think lots of people are really saying that Loki and Thor are so much better here than in The Avengers. Well, that is certainly true.
