Watched both and some thoughts
Wife really liked the first movie, we watched it - my first time. Then watched this one a few days later. The first movie was better.
-The movies were of similar length but the first one built a better story.
-Acting was better in the first one but she was older 14/15 years old in real life vs Lindsay (11/12).
-Second movie used a lot more comedy - the cheesy childish stuff from the 90s.
-The grandfather figure was better in the first one. When he found out that she was his long-lost grandchild, they did a better job of portraying his emotions and attachment.
-They cut out a few scenes from the camping trip e.g. the cougar sticks.
-Second movie, the comic relief nanny and butler - they were cute but not really necessary.
