It's not going to appeal much to those over the age of ten, and parents dragged along to see it aren't going to get anything of value.
The problem for anyone over that age is that there's nothing else to Home. The characters are flat, boring, and/or annoying, the plot is as basic as they come - and one late-game plot twist is so predictable that it really shouldn't have even been bothered with, except that it even further hammers home the "family" theme. Many of the payoffs are anticlimactic, the animation isn't anything special, and the voice work is more often than not inconsequential. Parsons and Rihanna sound like themselves and Parsons' character doesn't understand human ways and therefore takes things way too literally, which will just remind a lot of people of his character in The Big Bang Theory. That's a distraction for some and an annoyance for others.
What likely would have been more interesting would have been the focus on the Boovs' "benevolent" invasion of Earth. How the relocated/imprisoned humans react. Would we have a District 9 sort of situation here? We see a little bit of protest from the humans after they're moved, but not much more. The focus is too narrow and square on Oh and Tip to make note of any of the larger consequences. It's a kid's movie, so I understand why, but it's not wrong to hope for a better movie, especially when that premise is so ripe with potential.
It would be easier to like Home if it was funny, but I snickered maybe once throughout its 94-minute running time. The jokes are just bad, and they're not helped by the leading voice actors. Jim Parsons is Sheldon Cooper as Oh, and Rihanna is Rihanna as Tip. It's impossible to think of these characters as themselves. The writing doesn't help, the visual gags don't work, and it's just so unfunny from start to finish.
To be fair to Home, there's one sequence in Paris that lasts about five minutes and is quite enjoyable. It's a chase scene, involves a now-floating Eiffel Tower being slowly flipped on its head, and it's the first time when the film elevates its heart rate beyond resting. There's some creativity here, too, and for the first and only time the stakes actually seemed to be raised. So much of Home is focused on the two leading characters just talking about either how Boovs don't understand humans or how important family is.
There are children's movies and there are family movies, and Home falls quite comfortably into the former category. It's not going to appeal much to those over the age of ten, and parents dragged along to see it aren't going to get anything of value. It preaches how important family is, which isn't a bad message, but that's all it has on its mind. Parents should practice what it preaches and do something more involving with their children; that'll teach them the lesson with more impact than Home will.
Bottom Line: Very young children will like its color and how it tells them to love their parents, but it'll make anyone older than that roll their eyes.
Recommendation: Rent Lilo & Stitch or do something more meaningful and personally interactive with your child instead of taking them to Home.
