"Rocky III," released in 1982, was a significant hit both critically and commercially. It grossed over $270 million worldwide against a budget of about $17 million, making it one of the highest-grossing films of the year. The film introduced the character Clubber Lang, played by Mr. T, and featured a famous training montage set to the song "Eye of the Tiger." It was well-received for its action and character development, solidifying the Rocky franchise's popularity.

As of now, I cannot provide real-time streaming availability for movies in 2025. "Rocky III" has been available on various platforms in the past, including Netflix, but its availability can change based on licensing agreements. To find out if "Rocky III" will be on Netflix in 2025, it's best to check the Netflix library closer to that date or use a streaming guide that tracks movie availability across platforms.

"Rocky V" failed primarily due to its departure from the successful formula of the earlier films. Critics and audiences felt it lacked the inspirational tone and boxing focus that characterized the previous installments. The film's plot, which centered on Rocky training a young boxer rather than fighting himself, was seen as a downgrade. Additionally, the film's overall execution and pacing were criticized, and it didn't resonate with fans, leading to disappointing box office performance compared to its predecessors.

In "Rocky III," Rocky Balboa is portrayed as skinny because he has become complacent and has lost the intense training regimen that characterized his earlier fights. After achieving success and fame, he enjoys a more relaxed lifestyle and focuses on commercial ventures, resulting in a decline in his physical condition. This change reflects the film's themes of overcoming adversity and rekindling the fighting spirit, as Rocky later realizes he must train harder to reclaim his title and face a formidable opponent in Clubber Lang.
