Evidently Scooby Doo! Wrestlemania Mystery did well enough that a follow up was justified. Which I am pleased to see, because that was a fun film.
This is also a fun film, mind you, though like a lot of sequels it tends to retread a lot of the same basic material as the original, but writ a little larger. So instead of a major wrestling show, we now have a three day 'extreme off road race' with personalised vehicles for the WWE superstars participating. The whiff of Wacky Races is more than a little obvious.
The film's premise is that WWE is holding this extravagant race for a million dollar prize, and various of their personnel are taking part. The cast is rather an eclectic bunch. Major figures like the Undertaker or Triple H having prominent roles is no surprise, but the prominence afforded to Los Matadores certainly seems to indicate that WWE expected the tag team to catch on with their audience (spoiler: they did not).
In any case, Shaggy, Scooby and the rest of the mystery-solving gang are present at the event, and wouldn't you know it? An apparently supernatural menace appears to threaten the race. This is Inferno, who it must be said has by far the coolest ride in the film.
Though I do also have a soft spot for Rusev's locomotive-themed car
Naturally enough, WWE Chairman soon puts "those meddling kids" on the case, and hijinks ensue.
While lacking some of the freshness and charm of the first Scooby/WWE crossover, this is a harmless bit of goofy entertainment for the younger set.
