.... That's a very loaded question. Thank you, I can work with this.
TLDR; Yes and no.
So, HF is a weird theme for me in that I feel it had a lot of untapped potential. Like... a ton. Some of the others in the group disagree, but HF as a concept had more potential than I feel BIONICLE did, at least as far as being a long-running and successful Lego theme is concerned.
The scope was limitless, the range of possibilities almost incomprehensible. HF was setup in such a way that you could have any kind of conflict anywhere in the galaxy, under any set of circumstances, and the Heroes could be equipped with new gadgets and gear (AKA new Lego sets) to go and fight whatever threat they're up against. You could literally do anything within the universe and you wouldn't have to jump through hoops to explain it. You want to fight Fire Villains? Cool, give the Heroes Water/Ice weapons and send them off to fight the threat. Maybe there's villains in the sky so the Heroes have to be equipped with wings/gliders/jetpacks, or maybe there's an evil threat underground and they have to be given mining gear. Underwater, Frozen landscapes, Outer space, the Desert, the Jungle, etc.
HF may not have had as good of a storyline as BIONICLE did, but as a Lego theme? It had a ton of possibilities that were never capitalized on in any way, shape or form. HF failed for many of the reasons that G2 probably did; a poor storyline, a severe lack of marketing, and some management decisions that were questionable at best. HF's greatest shot at making a name for itself came in the form of Hero Recon Team, which allowed you to design and order your own models alongside custom printed instructions, a unique box design, and exclusive pieces. Unfortunately, I guess it never caught on, because the program was suspended pretty quickly.
Could HF make a return? Not as it was for the majority of its life, no. It failed for a reason, and I don't think it left behind enough of a nostalgia base to carry it forward. It would need to reinvent itself ot succeed again, and I think it could do that if it adopted the design philosophies of Invasion from Below and returned as a mech-based constraction theme with minifigures. Basically Exo Force 2.0, and at that point, you may as well just bring back Exo Force. That being said, I think HF, if handled properly, could have more staying power than an Exo Force reboot.
Ha ha, very funny.
Best villain of all time is obviously Jesse Eisenberg's Lex Luthor. Truly a legacy for the ages. In all seriousness, probably Wilson Fisk from the Daredevil Netflix series.
I really liked Star Wars! I'd be lying if I said I went crazy over it, but it's a very well told story with memorable characters and exciting landscapse. And how could I not love the prequel trilogy? Masterfully told stories with interesting and well developed characters, and-hahaha i can't keep going with that
No. No Martha.
