Deadpool proved you could make great sci fi movies on a lower budget with the right script. I think you can make a great Star Trek movie for 100 million dollars or even 80 million dollars, 180 million dollars seemed a bit high.
I guess the studio had it's reasons for giving STB the budget it ended up with.
We don't know and can only make semi-educated guesses.
I do agree entirely that a good Star Trek movie can be made for less than $180m.
Let's say $130m.
What is entirely lacking is a longer term plan for the Star Trek franchise.
If I were to have a say in things, I'd be planning the next 3 Kelvin movies on budgets of $130m (2019), $145m (2022) and $160m (2025).
I'd also green light another series of Star Trek films, not involving the Enterprise, to be release in between the Kelvin movies.
These could be smaller in scale and budgeted like a glorified 90 minute TV pilot for about $85m to $100m a piece.
All I'm saying is whatever Paramount is or isn't planning, continuing to think that a mega-budgeted film every 3 years is the way to do things, is clearly not the best way to increase cash flow.
