It's really sad how critics wrote this Christian Ditter film off. It's actually a pretty great family comedy, aimed at younger children, propulsive and colorful with a great message placed safely within a very mischievous faux-SF plot.
This science fiction aspect of the film is actually the easiest one to get out of the way. It's a gateway movie when it comes to science fiction and it's a nice introduction to chronomotion and stuff like Groundhog Day and maybe even Back to the Future. Of course, the real deal works are better and obviously the best version of this plot device but as an interpretation for kids, Jay Martel and Christian Ditter deliver a proper version.
So, any unfavorable comparison to science fiction classics of cinema aimed at older audiences are literally moronic. This film is actually doing a favor to the genre.
However the fundamental element of this film is not chronomotion. It's family values and the ability of family members to actually heal it and fix its issues. It's inspired by Parent Trap alright but it's an archetypal thing and Isla Fisher & Greg Kinnear play the main characters as a couple worth keeping together.
Kids are also pretty great in leading roles and Christian Ditter brings great proficiency to staging which is pacy and imaginative.
Mayve, the film fell victim to its perceived lack of Wokeness, even though there are elements of inclusion. But if you are on the lookout (no pun intended to Fisher's film Lookout) for quality family fare, check this out,
