I agree: I have seen the 5 episodes already and I really liked them. I didn't live the 80s from the XXth century, but my parents did and they say that they are very true to that period of time!
Yes, and your smart "free trial" idea really eliminates any (perceived) barriers for an individual to download this series on the other torrent sites. And as bbb noted, the sites mentioned here don't require membership, though you'll need to close some ad windows, and those can be shut down by using a VPN.
Maintaining a VPN would run about, say, $3 a month (dividing by an annual subscription) for the peace of mind that ALL of one's downloads, wherever, are anonymized. There must be dozens of threads and comments here (many by trusted Moderators) that explain the benefits of a VPN, and recommendations of particular brands. It's hard to reason why any thoughtful person would be so resistant.
I liked it well enough, as well. The huge budget cut that limited the use of effects pretty much killed it. Only really die hard superhero fans are going to watch a movie about super-powered characters that rarely use their abilities (or are shown using their abilities) because, well, what's the point? It sucks that happened.
