I find it so frustrating having to wait one whole week until the next episode. If they aired it nightly, it would keep everyone interested, and would save you forgetting to watch it the next week. Three months just seems a bit long to wait to find out the winner. 
In fact... to be honest, I wish they just aired all dramas and talent contests that have the same contestants each week nightly.
