This is a pilot for the Amazing Spider-Man live action television series, although it was released as a feature film in Europe. Overall, it is a good effort given the technically limits.
The acting and special effects are all good for 1977, the problem is that; 1. The witty humor from the comics is gone. Spider-Man is often making jokes while battling villians, but not here.
2. Uncle Ben does not exist. Hence Peter Parker becomes a super hero out of the goodness of his heart, and to take some photographs, and not because, "with great power, comes great responsibility." 3. No super villians. Many of the classic super villians would have been incredibly easy to recreate circa 1977; i.e. Chamelon, Kraven, Lizard, Mysterio. Instead we get a new age/guru con man and some odd ninjas. Beyond these problems, the pilot and the television series are a lot of fun to watch -- especially for Spider-Man fans.
