So many times with the serials and I have a ton on wait for it, VHS - so I have seen I believe a bunch of them, the poster art and lobby cards which captured the action-oriented scenes like a movie trailer, the actual 12-15 chapters fell miserably short. The cliffhanger endings were fun but again many were lame when you saw the out in the next chapter.
This one was really good and if I remember correctly, the Cap Marvel flying was a paper mache model propelled across a line. The Super serial used animation for that part so was kind of corny and very noticeable.
