The thing is, it's only bland depending on how you decorate.
I have white walls, furniture, wooden, uniform picture frames in neat gallery blocks. All my colour comes from bold furniture, cutrtains, cushions and throws, and the actual art in the frames. I just have very little of it to maintain space. I also have some wild wallpaper but in muted, tasteful colours and in purposefully deigned nooks e.g. built in shelves with candles that light the space up beautifully. I also have discreet diffusers so it smells wonderful.
But if you looked at it on rightmove, a lot of people would consider it a soulless, minimal white box. But when the lights are down, the scents are on and world is shut out, it's a cosy, clutter free haven.
The trouble is, people that hate the minimalist thing don't often appreciate how cosy and comfortable a home can be and how thoughtfully designed some homes are. Depending on where you sit in my lounge, your gaze may fall on the tv(!), art, plants, a small collection of books I want to read etc, all with beautiful bookmarks ready to use. There is also always somewhere to put a mug (on a coaster that I've carefully chosen), a blanket in reach. You just don't see it all when you walk in the door.
