Gandalf is looking great and him looking better than Joker is what I would HOPE happens. The same way I hope Batman, Pennywise and Aragorn improves as well. You usually have one of 3 things happen when it comes to new companies coming into the field.
They either stay stagnant, they improve or they decline. My bet is that INART will slowly improve in some areas while remaining the same in others. After all, there is a ceiling when it comes to mass producing these things in some factory. Hot Toys has long since reached their peak in terms of overall quality and have stayed in that consistent boat for a while, until recently of course with them trying wool hair.
INART will need to find their consistent ceiling as well. I think it’s clear they are near the top with their rooted hair but maybe they can continue to improve with the eyes, the magnets, the body, etc etc.
This is something you could see happening since Joker was announced. Whatever was their first figure, was always gonna be the first guinea pig to be compared to against every figure release that came after.
In the end, I rather see improvements than a decline in quality.
