Think Tom Hanks classic Big, the recent superhero flick Shazam! or Jennifer Garner rom-com Suddenly 30 - they're all heaps of fun and give you a little something to think about.

The latest flick to join the fantastical family is Little.

As you might expect from the title, it follows successful - yet mean and unkind - tech CEO Jordan Sanders (Girls Trip's Regina Hall) who is magically transformed into her dorky 13-year-old self (teen Black-ish actress Marsai Martin).

She is, rightly, mortified at her new state of affairs and calls on underappreciated assistant April (Insecure's Issa Rae) to help her figure out the situation.

As the trailer suggested, there are a lot of hilarity and silly hijinks in the film.

But, sadly, most of the funniest moments were already seen in the previews.

The concept is still great, but the execution leaves a bit to be desired.

Little needs stronger characters, better writing and clearer motivations for half the things that happen.

Some plot points hinge on people doing things that are incredibly unlikely.

Even one of the more memorable scenes - a (mimed) song and dance number - is so out of sync with what's going in the rest of the film it's hard to believe it made the final cut.

This being said, young Martin is fabulous in the lead.

The 14-year-old not only stars in the film, she also executive produces and is the very person who pitched the story in the first place.

She oozes confidence and class on the big screen and will no doubt have a strong career ahead of her.

While Little is not the greatest comedy in the world - or even among the top few released this year - it's still a half-decent way to spend an hour and a half.

The film isn't bad, it's just not brilliant. If you're looking for a brainless, easy chance to chuckle, then Little will hit the spot.

It's also tame enough for children to enjoy as well - the sexual references will completely go over the heads of most young'uns.

Also, keep an eye out for This Is Us star Justin Hartley - he's one of the highlights.
