Jeremy Renner returns as the dullest member of the Avengers. Fortunately, early episodes focus on a young apprentice, played by Hailee Steinfeld. Her character is as adept with a wisecrack as she is with a bow. But her performance isn't enough to make this effort as memorable as "WandaVision" or "Loki." The plot is more lightweight than previous Marvel series, which leaves plenty of room for inside jokes about the franchise, including a Broadway musical celebrating the heroics of Captain America.
