No, they wouldn't be.

The shallowness is exactly what makes it easy watching for large groups that can fit in whatever gaps they find with local preferences, combined with making it much easier for localised edits to be done.

Whether the movie includes comic book superheroes or not is not relevant - arguably, many a comic geek could probably point to reduction of depth in the plotlines in some of those. Same goes for typical US DoD propaganda pieces ^W^W^W^W Hollywood action movies, Disney reboots, "Butchered Love Actually Remake" CXXVII, and many other big budget plays that use this approach.

It works because while it's not a great meal, it gets you an equivalent of mcdonald burger in foreign country. Not great, not terrible, and the local adaptations probably aren't big enough to stop it from being "safe" choice.
