Really good watch, might watch again, and can recommend.
Having recently watched the original, this movie does a rather nice job of following it beat for beat. Now, it's not the same movie, but it follows the same format, with modernization and punch-ups throughout the movie.
As someone who complains about deviation from the source material, I approve the changes here. Sadly, they kept the twins carrying the movie, which means Lindsay Lohan was doing double work, but you could hardly tell. The green screen and clone work in this is actually really well done for late 1990's.
The most important aspect is that the movie retained its charm in re-uniting a lost / separated family.
