Is it good for re-using the same campaign in the marketing promotion?

For example, the 1980s' advertisign character for Domino's Pizza.

The Noid's birthday was also celebrated with an arcade game on the Facebook page, "The Noid's Super Pizza Shootout," a homage to "Avoid the Noid." Domino's gave away free pizza in the form of $10 gift cards to the top scorers.

To celebrate 25th anniversary, it would be a good idea to reuse the Noid once again.
It is a kind of a call from the customers' memory - the Domino's Noid.
Since the Noid is an advertising character for Domino's Pizza created in the 1980s,
the customers have good experience with the Domino's Pizza in their childhood, their youth and so on.

The marketing department re-use the character for a month only.
It is because they don't want to take a risk of drawing the young customers away.
This generation who is their main target likes new and modern stuff.

Nostalgia marketing can "save money" and "save man-power" rather than having a totally brand new campaign; however, it has to treat the old stuff in a smart way, like new design applied on the old campaign.  Does it need have the same budget?  If the marketing works on limit budget, maybe try another campaign in  another way.

Another example shows that nostalgia marketing may not be successful because of the trend changes.

Cadbury's 'Flake' TV Ad,  

the campaign focus on the beauty and delicacy of the Flake bar.  

In 1959, the flake girl showed her sexy.  

Cadbury's keeps the flake girl idea and try to present it a bit differently.

For me, however, it doesn't work.   I guess the concept of the sexy may have changed already.  The yellow stuff is turning around.  It looks like a jelly-fish which I cannot eat.
