and I enjoyed what Disney did with the Avengers movie
Disney's entire involvement was financial, you can thank the choice of Director and his choice of actors & story for the rest. Disney is probably at it's best these days when it find talented people and throws money at them and patiently waits silently in a corner for profits to come back.
if Disney have bought Lucasfilm and got Star Wars, have they got Indiana Jones as well?
Yup, they have everything Lucasfilm ever did. So potentially a share of the various videogame licences as well, although this doesn't appear to have been spoken about yet.
My overall feeling is delight and trepidation in equal measure. Lucas just seemed more interested in what
could be done than what should be done and surrounded himself with yes-men (and women) who decided he could do no wrong. As an earlier poster said, the technological innovations of his companies are more impressive than his writing/directing will probably ever be. I'm not actually sure THX & ILM is part of Lucasfilm so perhaps he'll even retain ownership of that side and continue his tinkering.
My second thought was $4bn dollars was an insanely cheap price. Even if Disney never released another second of Star Wars/Indiana Jones media, they now own the merchandising rights and can sell lunchboxes, cereal, t-shirts and whatever else enters their head and recoup that investment quickly, especially considering their already established distribution channels & stores.
And my final thought was "Oh *&^%! Why
them". The Evil Empire appears to have crushed the Republic at long last. Pixar has never been the same since their 'merger' with their last two films being "Disney" more than "Pixar" and I expect similar child-like regression of the SWToR licence. Perhaps a Younglings meets Barney episode. "I love me, you have no emotional ties as they lead to the dark side, we're a happy family!"...
