Getting writer's block on writing the action scenes.

After finishing most of my script, all I have left is the action scenes. It's a an suspense/thriller script with crime and action involving crooks and cops.

I structured it after a lot of action and thriller movie story structures. However, I find myself uninspired or indecisive, when it comes to writing them. Mainly I am writing for an extremely low budget, which limits the creativity of what can be done, action sequence wise. So basically it's like El Mariachi, where you don't really go much beyond, people running, people getting stabbed or shot, and that's it. But even that gets old, and the shootings have to be quick and simple, since the low budget cannot afford squibs to express blood or anything much like that.

So I am wondering is there a particularly way I should approach the action style and tone... One thing about low budget movies, is that the horror genre is very popular, and can be achieved without near as big of budgets compared to other genres... at least in the audience's eyes, since most audiences accept a lower budget, if it's a horror movie.

Basically I see the script as a crime/thriller/suspense/action/drama genre. So maybe if I were to take out the percentage of the genre combination that is action and switch it to horror, maybe that would be better.

Maybe audiences would accept cops and crooks, battling each other in horror sequences rather than action sequences. Maybe I can do something new.

Or maybe they will accept it less. What do you think?
