We have the Disney-level Mega Movies with ONE BILLION DOLLAR budgets. These are the ones that are made by a committee of producers and executive producers and shareholders. They're too big to fail, so they'll be tested and re-tested and re-shot until they WILL make a profit. Currently they will also include a Chinese movie star and won't touch any subjects too sensitive for China, because multiple tens of percents of profit will be made in there.
Then we have the Blumhouse[0] type 5-20 million dollar movies. They give a hard budget limit and won't pay the actors much - they'll get a share of the profits instead. They're cheap enough to not bankrupt the production company if it flops, but will make immense profits if they succeed. The Company won't usually affect the production much, giving the director free reign to do what they want.
What's missing in today's world are the $10-$100M, movies. These have a big enough budget to not have to cut corners much, but still small enough to not draw the attention of The Executives who want their favourite things in the movie - letting the director enact their vision. The only mid-budget movie I can think of in the recent years is Michael Bay's Ambulance[1], shot with $40M.
