This sorry excuse for a movie is an utterly diabolical, shameless travesty; an unforgivable insult to the franchise, particularly the excellent first Home Alone movie, that it has unsuccessfully tried to recreate. Having already been cloned twice, each time worse than their predecessor, you'd have thought that it was time to stop milking this plot drier than it had already become. But no, they had to flog the dead horse one final time.
No child actor could hope to match the pure class and acting talent demonstrated by Macaulay Culkin in HA1, and to a lesser extent HA2. Mike Weinberg isn't even in the same league. This is probably not his fault - he was only a 9-year-old boy that was the victim of terrible film production at every level. Even Culkin (at the same age) couldn't have stopped this from being a steaming pile of plagiarised donkey droppings. Which raises another question - how is Kevin McAllister 9 years old in this movie when he was 10 in HA2? And the actor used to portray Marv isn't the same one from the first two instalments?

Do yourselves a favour and avoid this at all costs. Watch HA1 or HA2 if you want a Home Alone fix.
