I for one enjoyed it. It's not a great film but I did not think it that bad - and it has a few nice homages to previous versions.

The total dearth of other new films out may well work to WW84's advantage, but I still rate it better than Justice League.

There is exactly one bonus scene at the end, quite early in the credits (if you see the special guest star entry you are past it) so unless you are interested in the credits (which I try to be for all the hard working people) there is no need to stay to the end.
