Take the Star Wars line for instance. The star wars line of PF's and statues have had characters such as basic stormtroopers, clone troopers, speed biker scouts etc.
I don't see why the lotr line shouldn't extend to characters such as Galadrihm Archers, Gondor soldiers, or even Rohan Royal gaurds.
As long they are done well and look kick @ss they will no doubt be well recieved.
You can collect Luke Skywalker in about every possible wardrobe change, (not that that's a bad thing) The lotr line could even look at doing another Aragorn, if it wanted to concerntrate on principle cast. Say, in his Black Gate costume with Anduril?
In a way I guess it
does depened on how fanatic you are about the franchise. But in the end, I can always see a generic character, like a soldier, getting great reception, provided that the final product is an awsome maquette/ PF or whatever.
The Beserker is kind of generic, in that it's just an Uruk-hai. But that PF is - in my opinion - the flagship of the lotr PF line.
It has an on-screen time in one of the three films of about twelve seconds lol. Yet look how well recieved it was as a PF!
Never rule out the possibility of generic or background characters
