I find public prayers incredibly boring and I never go to the synagogue.
maybe what you experienced is like in britain, we have large shuls with a slow service.
find a younger congregation, like people < 40 or < 30. The number of people is smaller, and the davening is more energised.
their entire philosophy is different.
Large shuls, are often old, and from an older generation, the davening is often s-l-o-w, all drawn out, and you either have a proper chazzan, or somebody that thinks he is a proper chazzan, and a congregation that wants a proper chazzan and may be nostalgic for one. Lots of chazzanut. Not much participation from conregants. Lots of them sitting around listening to the chazzan's voice. The style is going out of vogue. The generations now are more religious thanks to jewish outreach organisations, and they are more interested in focussed davening than the chazzanut.
A rabbi once made the observation, he referenced the beginning of the amida (elokainu velokai avotainu..), and said that there are 2 ways to follow G-d.
following the g-d of our fathers, and following your G-d.
the 50+ generation were following the G-d of their fathers, just wanting to be traditional.. (I think he was being polite, he didn't want to offend the people of 50+ that he was speaking to).
The <40 generation(s) are following Their G-d. they have personalised judaism to suit themselves (within the boundaries of orthodoxy).. they have made it their own. (it seems to me that the slow drawn out service is more of a "i'm doing this bit of suffering each week , paying the price, that's my bit, so i'm staying within the fold, so my father won't turn in his grave". It's not much of a religious experience).
There are some religious people in big shuls, that pray every day but still they don't mind a sing song if it's only once a week.
How people pray on a regular morning in shul is completely different, much faster because they want to be ready for work. So even a big shul will get it over and done with.
