So it is a Space Opera?.....Musical thing seems a bit odd....but to be fair Batman had a quite a few original songs (and a cover of man in the mirror) so music is becoming more important to the Lego movies.
I personally hope he is wrong. I love this game. My hope is that if the game is dead (which I hope is not true) that it either resurfaces in a new form, or that Lego finds some other way to release small sets like this for licensed characters that cannot sustain a full line. We would never have seen Gremlins, or ET were it not for Dimensions and the game is fun to boot.
I do actually watch the Ninjago show with my kids and collect some of the sets/minifigs, but I am perfectly okay with a Lego Movie universe take on Ninjago.....it seems like a lot of people are upset about the changes. I personally think this might be more in line with the Lego Movie than Batman will be to be honest (love the use of some of the CMF minifigures in the preview.
