Like another poster mentioned, it was a made-for television movie and there isn't one thing about the production values that says differenty. I'll wager that the budget was divied up four ways: 1) Hayley Mills, 2) Tom Skerritt, 3) the few 'double shot' effects so we can see the twins together, 4) and the rest went to the actual production.
The script isn't as good as the first, but it does have it's own charm, and you can't deny the various winks and nods to both the original movie and Hayley Mills.
When you see the production values for part III and Hawaiian Honeymoon, they actually make part 2 look almost theatrical.
Only good thing is to see Hayley Mills reprising her role. Story is unbelievable... Why make the other twin married? Would have been better to make her single.. why waste her time? If her sister was interested in a man, she would go after him without help!!! Story is a big problem. Guess when it was released no one cared, just excited for a sequel to parent trap.
Agree that Parent Trap II would be better if both sisters were single instead of having the one sister married but flirting with another man. On the other hand, at least the hijinks are much less malicious than the original and it doesn't promote violence. So while it still has plenty of flaws I enjoyed this more than the first one.
