The Mummy Returns is a film that, I think, you need to see the first film of the saga because otherwise you don't understand some little details. That film is a film like Indiana Jones with the same plot and the same characters. But the kid is an exception. The cinema show us the kids like boys and girls insufferable, but Alex O'Conell is a boy that "pass more time in the museum that in house". One difference this film have respect Indiana Jone's films are the sobrenatural characters than appears like The Scorpión King or Imhotep. If you like Indiana Jones and Egyptian mithology, I recomend you that film
