Why are church services usually boring?

[Der/die AtheistIn]

If you don't find them boring, you have the right to have your own opinion. Most christian churches tend to have boring services. Why? I understand they were made thousands of years ago, when the population was mostly illiterate and have very little if any scientific knowledge and very little entertainment. I also understand that prejudice and herd mentality were a lot stronger. But wasn't this kind of service boring even for their standards? Not that I hate the boring part that much, it makes it at least for some people - including me - unappealing to resort to their childish superstitious practices and beliefs. Even if I didn't want to accept the fact that death is eternal, even if I wanted to fool myself to get happiness, I would've at least chosen a more interesting option. 
Why are the priests talking so monotone? Religion bases itself on feelings.
Again, I don't wish to change it, I just wonder why this is the case.
