I actually liked the first Jumanji, and I looked forward to seeing second part of it.
I thought it would be a lot better since I like Dwayne Johnson.
And I agree with your grade of 6.5.
It's a solid movie to lose some time, but I'll probably forgot it 2 days later.
Yes, we see completely eye to eye in regards to this movie. It does the trick when bored but just don't have the energy to think too much, lol! :)
