This has been discussed in various forums (including here), but the bottom line is that no event has ever repeated yet. If you'd like to get the content from that event, you have to wait until their legendary chests come back for a limited time. For example, "Nightmare before Christmas" chests are available for the next few hours. The drawback to this is that a chest costs either 60 gems for one or $9.99 for six. If you spend gems, you have no guarantee of getting anything more than a decoration. If you spend money, you're guaranteed one good item from six chests. It's been lamented by many players that it's not worth spending either money or gems for anything more than a chance to get something you're missing.

The good news is that with the new Maleficent events, it's possible to buy specific characters and buildings with Maleficent currency, but you don't get to choose. Also, with the start of these events, the daily prize will usually give you one legendary chest for free.
