I liked Blue Swat, it's really the only '90s metal hero show I like. The earlier episodes are best, the later episodes are a mixed bag because they played around with the tone of the show so it would appeal to more of the younger viewers.
After metal heroes had a personality crisis starting with Jiraiya, Blue Swat was a nice return to its sci-fi roots, yet was still in the "realistic" style that the Rescue Police shows tried (and kinda failed) to pull off, and that made it unique.
Ah, leave the OP alone. It's a good song, and a change of pace similar to the Metalder OP (although the Metalder theme is superior).
The ED theme...now that's horrid.
