If you were looking to add data, and certainly it's already appreciated as-is, budget is always relevant. I assume production budget at least is usually not too terribly hard to find.
I agree! I've definitely thought about adding those. Lately there's been a lot of conflicting info about budgets, but I suppose I could always add ranges, like $150-200M, like Wikipedia does, if there are multiple legitimate sources for budgets.
Feels like BB is a victim of WBD's broader lack of strategy with the DCEU. At this point audiences either don't care because they know the whole franchise is getting rebooted soon, or they don't care because they're just not that interested in anything that isn't Marvel (and even with Marvel, audiences are becoming noticeably more selective).
