Show is developing nicely and although the build up is slow, by episode 5 the story progresses more and gets interesting. World building seems good, characters are solid and there's an eerie vibe in every episode which makes it intriguing.

Also, this show is somewhat different; many double meanings and implications. Feel free to interpret. Wandavision is already a pun.

On another note, I am happy to see many actors from various MCU films appearing. Also, the core cast of this show is pretty good (see Kathryn Hahn) and OlsenBettany are given a nice chance to show some more acting skills and deliver comedy on top of the drama and action that we are used to.

So, its an 8/10 for now, looks like a novel show. Give it a go.
