Just saw the IMAX 3D version a few hours before this post and I have to say that this is a good movie with some twists that will surprise you no matter what you know of Loki or the Marvel Universe in general. There is also a surprise cameo that I will not spoil. There are also TWO big reasons to stay until the credits finish: one I did not get as I have not been involved in the Marvel books in two decades and another that is both touching and funny. Again I recommend the movie especially if you liked the first one. :)
