Not actually terrible. That's not to say it's anything close to good, but it did surprise me ever so slightly; especially after an extremely ropy first 5-10 minutes.
Ricardo Hurtado (Tyler) is OK as the film's lead, while Alkoya Brunson (Eric) has most of the somewhat amusing moments. The premise is watchable, though only after the awful initial school scenes that made me fear the worst. Once they reach Malibu everything does move in the correct direction - still with some major issues, of course.
There's also a running gag throughout featuring Michael Mourra (Jeffy), which is mildly funny; he's used for the predictable interludes, but it is done in a way that is kinda different. I appreciate that.
Great call making 'Malibu Rescue' run for just 69mins, any longer would have deteriorated my rating massively. I see this has also turned into a television series, I'm not sure I could put up with it for 8 episodes; though I'll probably return when the sequel film is released.
