They weren't wearing bras and you could see, well...at least that was the justification one of the Angels gave for their popularity in the documentary series on the 70s.

But, going beyond that, it is totally 70s fun. The plot is out there, at least enough to make it pretty fun in the not at all realistic sort of way.

But, one you move beyond that, it's one of those wonderful late-70s-mid 80s detective shows, albeit it this one has a male fantasy premise and cast.
