It's definitely an apt comparison. It's amazing how Marvel continuously gets to have its cake and eat it too by having an insane built in fanbase for these films that's probably the most loyal atm but also is seemingly accessible to everyone else.
Tbh would DC even add on that much value to an Avengers Film? Not a knock against DC as they really taking some good strides recent and Aquaman did make $1.14 Billion but seems like the MCU Films have elevated the Marvel characters into the zeitgeist.
