Will I still enjoy this if it has been spoiled for me?

The twist, as you say, is kind of handed out early on, and isn't really the main event here. So: maybe?

You could also just watch enough other stuff first to forget about it again ?

The show was spoiled for me as well,  but I still watched it, I think it is worth it. There are many twists in it so you would definitely still find it very interesting

It might be fun to notice all the hints the director was giving
