Once again, Superman returns to our screens, this time played by British actor Henry Cavill in Man of Steel. Cavill is joined by many other famous names, such as Kevin Costner and Russell Crowe. Michael Shannon plays Superman's enemy, General Zod, and Amy Adams is curious reporter Lois Lane.

Man of Steel takes a closer look at Superman's past, where he was born and how he found out about his amazing powers. Viewers will get to know Superman's family and the events in his childhood that made him become a hero for good.

The script is poor at times and some of the acting feels forced, but the special effects are fantastic. There are a lot of impressive fight scenes between Superman and his enemies that are sure to take your breath away. If it's adventure you're looking for, Man of Steel is the film for you!
