Ignore all the bad reviews on here this is a really great movie for kids and teenagers to watch. The CGI in this movie was great. Voice actors for the alien voices were pretty spot on. The acting for this movie was great. I am not going to spoil anything but I am going to say if you want to have a good Sci-Fi movie which both kids and adults can watch i would recomand this film.

I must say, I loved this movie! Everything about it was just right. All the characters were funny and lovable, even the bad guys! even the aliens and the boyfriend. I thoroughly enjoyed watching this film. All I expected was jokes and slapstick. I got that and much more. At times I even found myself holding my breath. Its unusually tense for a children's movie. There's always this underlying threat and the movie does not let us forget it. And that's what makes this one that much more fun to watch. There's plenty of eye candy if you are a girl in her teens like me. The two main characters, Tom and Jake, were my favorites. I loved these characters so much that its so hard for me to choose between them. All of the Pearson cousins had something special about them, and that's what makes each of them so lovable. The witty dialogue and funny references also added to the movie's fun factor. I think this movie is painfully underrated and I suggest you give this one a go. You won't be disappointed.

I only write this review because I see all the hate for it on IMDb. Really what were people expecting from it? It was *supposed* to mindless fun!I watched this when it came out on theaters with my cousins. Two of us were older (in our late teens) and the other two were in their preteens, and we had a really good time. It was perfect bonding time because this film was about a bunch of cousins!Sure it had all the kid-movie clichés (e.g. grown ups are too dumb to realize anything is wrong), but it was fun, it was genuinely funny, and for a movie called "Aliens in the Attic" it had a surprising amount of character development. All the kids grew as characters throughout the movie and even the aliens had some character growth! Nothing deep, yes, but I was surprised that it was even there!Besides, when else will we get to see Raymond's mom kick some alien ***?

I've recently seen a series of poor productions for kids, so I know for a fact this one is better than many others. The characters are well written and the actors do their job well, both the young ones and the older ones. The story has huge plot holes, just one example is the language the aliens speak, they seem to have trouble with English but on the other hand they speak it among themselves. There're more such goofs but I can't specify without adding spoilers, so I'll just say, that despite this fact, since the characters themselves are real and convincing, the whole thing does work, it's quick enough for the viewers not to notice these inconsistencies and it is funny and exciting. All together - not a bad viewing
