Yes, Ocean’s Thirteen is the third (and hopefully last) in this series of movies.
This one really wasn’t too complex (i.e. disappointingly no real brain power required to figure out the minor twists), though entertaining enough. It wasn’t really that funny either. I think we’ve all become just too familiar with the banter between Danny and Rusty and the play of Linus as a parallel running character. Watch it if you liked the first two, but don’t expect something better.
It’s been a less-than-stellar sequel run this year overall. Of course there have been a few opening records set. What amuses me is that all the professional reviewers seem surprised that sequels don’t have any staying power passed the first weekend. Perhaps it’s because they are highly anticipated but not that good, plus they are all coming out one after the other each weekend stealing each other’s trailing thunder.
So in terms of major franchises, I think that leaves Fantastic Four, Harry Potter, Die Hard and Bourne to give it a go this summer.
