I always enjoy it. First season is a bit more gritty than the others but I always think its a pretty fun show.
It was my understanding that studio was asked to turn the violence down after S2 as such the plots were less violence. I have watched the pilot a few times as it was done very well! There are some really good episodes over the seasons, especially when something happens to either Starsky and Hutch's character (i.e. shooting, sickness, etc).
The two part segments, especially the boat cruise or LV strangler or other episodes were ok, but could have been much better when it came to either the acting or plot development.
