Basing judgement on ranking is a fallacy, since ranking is entirely based on competition, and there are many more factors to box office gross than competition.
I implore any anime watchers here to watch Steins;Gate. Probably the best time travel story I've seen anywhere including books and other media. It just requires a lot of patience to go through for the first half, when it is basically setting things up. After you finish the series though, probability that it'll be in your top 10 list is over 95%.
Ah, long time no see, BOT.
Btw, people who are thinking 900m+ OS is the floor for SW7, you are mistaken. Obviously its possible it can make that much, but considering SW is nowhere near as popular as some franchises like the Avengers and even Transformers and they also just barely managed near 900m with recent titles, 900m is nowhere near locked for SW.
