For some reason that I'm not yet personally aware of, I decided to seek out and watch the original (or technically the 1960's compilations of) Flash Gordon series. I'd long heard about how influential this serial was (along with the original Buck Rogers as well) so I figured I'd give it a go to have some first hand experience with it. What suprised me the most was that I couldn't shake the feeling that it most reminded me of modern scifi fan films in terms of pacing, script, and acting. I'm referring to the true FAN films as opposed to professional productions emulating the 60's or 90's shows staring veteran actors (both from trek or other IPs). The lack of to incredibly rushed setup for both plot and characters, the stilted infodump dialog, seemingly one take action scenes with no real literal impact, etc remind me of the recent (i.e. last 10 years) of Trek fan films. There isn't a way of saying this without it coming off as too negative (and I do truly enjoy fan films for what they are... fans doing their best living out their fantasies communally for others to enjoy) but I really couldn't stop seeing the comparisons. I suppose the limitations (both time and financial) of those old serials were similar to what the most funded true fan films experience today but I figured I'd mention it here and see what others think. If you're interested in watching them legally for free, they're on https://www.imdb.com/tv/ under the scifi movies section. I watched the original one where Flash, Dale, and the professor go to Mongo the first time. It's also available likely on most amazon prime streaming apps since Amazon owns IMDB.
