You are talking about sentimentality, the Eucharistic sacrifice of the mass is not a sentimental re-enactment, but an oblation of grace for communion with God, physical, spiritual and mental communion. God became man, physically, spiritually and mentally incarnated so that we may be uplifted and become like God. It is called deification in the west and theosis in the east, but it is the whole point of our faith. 

This is alone attained by cooperating with Gods grace as is given to us primarily through the sacraments given to us by the perpetual sacrifice of Jesus Christ. 

I truly recommend reading about the mass and its origins why certain prayers are present and in general what is going on. Coming from an atheist background when I became a seeking deist I read a lot because I wanted to understand what the point of the mass and the other sacraments were. If you need help finding some sources let me know the theology of the mass is so central to Catholic faith so I hope you consider.
