I was never impressed with the old WW show. Maybe its becuase I've only seen season 3 episodes and it had gone downhill by that point. But from what I saw the show was basically about a different one shot "man of the week" who would do most of the stuff, while WW would pop up usually once in the middle and once in the end of the episode to save the random guy. When Diana was the main person of the episode, you still mostly had lame shenanigans and Wonder Woman would only really show up for about 2 minutes total, unless she was doing something stupid like skateboarding.
Also, while I didn't expect Batman 66 action, WW's "super feats" were generally pathetic (lightly pushing criminals all of 10 feet, jumping off of things), and that's when when they weren't completely asinine (the various gimmick suits).
Don't get me wrong, I like a good goofy old show sometimes, and I think Lynda Carter would fit perfectly in a WW show of the era. But in the actual WW show itfeels like the actual title character was an afterthought, and they'd have rather just made a generic show about stopping criminals with Diana Prince, without powers/costume, as a supporting character.
