"Superman III," released in 1983, frequently receives criticism due to its use of slapstick comedy, a parodic feel, and the involvement of Richard Pryor, but it manages to be enjoyable after adjusting to those elements. Christopher Reeve’s portrayal of Superman is naturally well-done, and the movie also features Robert Vaughn as a villain reminiscent of Luthor, alongside Pamela Stephenson in the role of his appealing female assistant, similar to Miss Teschmacher. The acting generally stands out, especially with Annette O'Toole playing Lana Lang, who serves as a substitute for Lois Lane, whose screen time is minimal; she’s lovely to watch throughout. After getting past the overly silly nature of the film, it becomes quite engaging in its second half, depicting Superman battling his darker impulses—a clear representation of the internal struggle between our physical and spiritual selves. There's also a gratifying return to grace for a particular character that demonstrates how someone can commit a significant error and still be worthy of forgiveness, provided they are open to it. The movie ultimately leaves you feeling good. Ultimately, it’s not as strong as the initial two installments, but "Superman III" is worthwhile if you set aside all the negative comments and give it a try. Richard Pryor's performance may seem silly, yet he's endearing, while Annette O'Toole truly impresses. Above all, the film possesses a depth that isn’t immediately apparent and effectively communicates profound insights about human nature and what we are capable of. The movie has a running time of 2 hours and 4 minutes. GRADE: B-/B
