Improved and larger Dungeons in the Caves and Cliffs update.

Overview - The current dungeons are tiny, lack content and have highly mediocre loot. I've never ever felt like "Oh dungeons! I love these" and then going out of my way to find one. Dungeons should be much more, they should be large, have many rooms and areas to explore, they should excite the players and encourage adventure.

So how could the dungeons be improved?

Suggestion Number 1 - Bring their aesthetics up to the standards that the newer structures in Minecraft have, example: The new villages, Shipwrecks and Bastion Remnants! Those structures are already among the most aesthetically pleasing structures in Minecraft, and older structures should be brought up to that standard.

Suggestion Number 2 - Improve the gameplay of these dungeons by en-largening them; making them larger, exciting and fun to explore. As an add-on to this, add more mobs that spawn specifically in the dungeons and/or strongholds! These mobs could be more powerful and challenging, present a challenge to the structures. But with the increase of difficulty should come an improvement to loot, with the chance to find valuables such as diamonds, armor, other valuable items etc.

Finally; Why do I want these improvements to be made?

Because Minecraft's current cave structures aren't very aesthetically pleasing, they lack adventure and don't bring much value or excite the player enough to encourage adventure/exploration.
