Home Alone 3 is a fine movie, it is heavily underrated because
- the first two are christmas classics
- the two that came after it were cheap and bad straight to dvd movies (also the disney plus one)
It follows a new cast (which isn't even bad, especially the kid) in a new scenario which also might be the reason of why it is ignored but i think it's for the better, there's so much you can do with kevin getting left alone. The movies premise is funny in itself, a bunch of global terrorists have to find a chip that can control missiles because they have mixed bags on the airport and now they go through every house in a suburbs looking for it ready to eliminate everyone who comes their way, ofcourse they end up like marv and harry which in this situation is also bit funnier. While you could treat it as a negative it didn't bother me personally that much, it isn't a christmas movie as much it is a movie that takes place during christmas season, most of the tracks are also more in tone of the terrorists on a stealth mission which is also funny and the trap prep scene has Home Again By oingo boingo which, despite liking the original prep theme i think it's one of the best tracks of all time, doesn't bother me again because i really like oingo boingo.
Overall it's a good movie that is unfairly thrown in to the trash pile with other home alone movies, sure it isn't Home alone 1 and 2 but it's fun in it's own way, i reccomend you give it a go.
