The Griswolds are back, and this is easily their worst vacation yet. I don't think it's as awful as some do, but yeah, it is really dumb, tired, dull, and overly reliant on formula. And also devoid of contributing anything new.
I still give it some credit though, because it does have its moments, even though I really don't want it to continue after this.
Featuring new kids but the same parents (a series tradition), Clark decides to take the family to Vegas where, besides having lots of fun, he also plans to renew his wedding vows to Ellen.
As you'd expect, all sorts of trouble and shenanigans ensue, all of them with predictable results, but at least this time each Griswold had their own subplot, which doesn't often happen.
The movie does have a decent amount of laughs, but it's definitely more misses than hits. At least Quaid is back, and we do get some great cameos and special appearances, most notably Wayne Newton and Wallace Shawn to save things, so that's good I guess.
Overall though, this is just run-of-the-mill blah, and nothing really all that special.
