The actors and FX are fine but the writing is awful
It's entertaining. I would call it a guilty pleasure. Some episodes are really good, some are meh, it depends.
But it's a fun show, and I like that. I think people forget comic shows can be fun as well as dark and serious. There needs to be a balance. Not everything has to be The Dark Knight.
So if you can make a fun show with people dressed in costumes, it's fine.
Sorry to burst your bubble, but LoT actually has been renewed for a 3rd season...
