I too felt the scene itself was a little cheesy, specifically the lyrics of the song, even though I liked the message of hope and all that. Skip warranting? nah.
The religion in Thedas debate is always a fun one. I thought BW did a (suprisingly) good job at catering to the middle ground for their audience in terms of religion vs atheism, especially after all the screaming threads by the DA2 community saying down with the chantry, I hate religion blah blah. Afterall, you cant convert any1 nor sway any1 against the maker. At best, your character can say "yes" or "no" when asked, with very little force behind either statement.
Theres not much BW can do if you want to try and interject your own modern religious/anti sentiments into the the character in an entirely fictional world. I think they already did enough retconning of the cultures and peoples of Thedas to try to appeal to their new audience.
Its so weird to look at the shifting BW community as a whole with the new gamers coming in and the old ones getting out, and the devs as well.
