Have you tried creative mode, gives you access to more block types so you can build more. Also joining a server with friends can be more fun, building a shared world where you can make simple or complex structures.
Personally I prefer to play in survival with monster off, 'cause I’ve have a few too many close encounters with creepers, but some of my friends like to use creative to build huge structures and on a shared server I built a large underwater pyramid with secret panels and had fun looking round at what others had built.
In the end not everyone has to like the game since if we all liked the same thing the world would get dull fast.
