まじめ is this bad thing?

Question:

I was told I was まじめ by a friend is this good or bad??

Answer:

It depends on what situation you were told to be まじめ.
Of course まじめ is basically good character that means to be polite, serious, having common sense.
It sometimes, however, means boring person because まじめ person doesn't behave flamboyantly, excitingly, adventurous.
Perhaps those behaviour is expected by people, but まじめ person lack of it.
