You bet it can. Especially if you do not view them back-to-back. Usually the first in a series is fresh and surprisingly different. It is not an easy thing to keep up the momentum. Well in "National Treasure II" they added momentum. It was great keeping all our old friends and seeing how they progressed. It is not that Mitch Wilkinson (Ed Harris) does not make a good villain, but I was sort of hoping that Ian Howe (Sean Bean) would have escaped to create more havoc. This film was packed with great actors but I think that the character Prof. Emily Appleton (Helen Mirren) was a double plus good edition.
Basic story is that the Gates family is once again besmirched by the mysterious Mitch Wilkinson. And the only way to clear the family name is to find the city of Cibola (see-bowl-uh) meaning the City of Gold. All his old comrades and some new ones, including mom, pitch in to help. Let's see what mischief they get into and will they get out unscathed or is this it for our adventurous troop.
