I tried watching SWAT and found it tiring, since almost every episode ended in some kind of action set piece takedown. Done on a TV budget, those setpieces tended to be underwhelming. The show being in a theoretically realistic setting started to clash with the team getting in so many high profile gunfights.

I just don't think the formula exactly works. There's two directions it could go to be great. One, turn it into The Shield with some quality drama and running plots with heavy themes. Two, turn the city into a Robocop/Predator 2 type over the top hellscape with absurd overarmed gangs of cackling thugs roaming the streets, and acknowledge the absurdity of weekly giant gunfights by folding into the setting.

I doubt the show runners are brave enough or interested enough to do either.
