Well, I can't say favorite but the scenes I've had enjoyed was:-
a) When Ralph got mad outside the eBay store and break the media screen and threw it and then it smashed a user avatar and her internet connection lost.
b) The race between Vanellope and Shank.
c) How they represent internet ads process system.
d) Placement of eBay, Amazon, Pinterest, and of course the entire Walt Disney Company.
And about the takeaway from the movie was:-
As long as the person that loses the most is self-aware he/she will eventually win.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
