I think it's interesting to think back that in 2005 Batman Begins was considered a bit of a financial disappointment, underperforming though not outright failing, even though the critics liked it and the comics fans liked it or loved it; I think the general explanation was that B&R was so bad that a lot of people avoided BB or were otherwise just not interested in more Batman films even eight years later and even with the marketing making it look really different. And also to consider that then just three years later TDK was a huge financial success.
