When the Mystery Inc. gang is invited to Spooky Island, a popular amusement park, they soon discover that the attractions aren't the only things that are spooky. Strange things are happening, and it's up to Scooby, Shaggy, Fred, Daphne, and Velma to uncover the truth behind the mysterious happenings.

'Scooby-Doo' offers nostalgic value with Matthew Lillard's praised Shaggy portrayal. The film is appreciated for its faithful character representation but criticized for a weak plot and subpar CGI. Deviations from the cartoon's formula and inconsistent acting are noted. The humor is seen as juvenile, and the blend of kid-friendly content with adult humor is both a strength and a flaw. It's an entertaining yet flawed adaptation appealing more to original series fans.
