The Marvel Cinematic Universe, a once-mighty franchise that could seemingly do no wrong, has been on the proverbial ropes for a little while now. Sure, it's continued to find success — look no further than the billion-dollar juggernaut of last summer's "Deadpool and Wolverine" — yet in showbiz, you're only as good as your last hit, and this past winter's "Captain America: Brave New World" didn't exactly light either the box office or Rotten Tomatoes on fire. Fortunately for Marvel Studios, they have a couple more films to offer up for audiences' favor this year, and next on the assembly line is "Thunderbolts*." While "Brave New World" felt like a reheated "Captain America" adventure awkwardly grafted to a "Hulk" movie, and this summer's "Fantastic Four: First Steps" is a long-awaited return to some of Marvel's most unfairly maligned legacy characters, "Thunderbolts*" has felt like this year's biggest wild card of a Marvel movie.
