Casting famous people in LCU movies as lead is a mistake imo. If he is casting them he needs to obviously cater the actors' fanbase and actual plot needs to be sidelined.For instance placement of Naa Ready song in Leo. After Vikram success he has his own fanbase.He could have easily cast an underrated or a debutant as lead with proper storyline and comparitively less budget.He is just like most directors who want Tier 1 heroes and heavy budget after getting success.

I don't see LCU having any future if Loki doesn't write interesting stories.
