I loved Superman. The spectacle. The acting. Reeve was so charismatic and Kidder was adorable.
Superman II not as much. Didn't really like the villains. And got too much of a been there done that vibe.
Superman III was terrible. An embarrassment. Richard Pryor totally destroyed the movie.
Superman IV was so cheap. But entertaining in spots. At least it wasn't Superman III. I did like Lenny Luthor.
