OP - try a different church - ours is nothing like that. Our church has 3 services a day all with about 400 people.
Family service, lively with a band, dancing, sometimes people acting, video clips, a talk from the vicar and worship songs, children's groups from babies to teens with crafts and games for little ones and breakfast and discussions for the teens.
Coffee/tea afterwards. 11am service, traditional wording reading from service sheets, old fashioned hymns with church organ, communion every week. Tends to be popular with the elderly. Tea/coffee and cake after.
Evening service, very modern and lively, snacks after, tends to be full of youngsters and young adults, students from local uni.
We also do weekends away, quiet worship, women's groups, men's groups, older peoples groups, mother and baby groups, toddlers groups, Messy church, small groups in peoples houses, support groups, alpha groups, parenting courses, marriage courses.
Service wise (together with other churches) we run the local food bank, night shelter, lonely peoples lunches, Street pastors, counselling, debt counselling, tradecraft markets, a work scheme for adults with learning difficulties, support an orphanage overseas and of course anyone that needs individual support. Probably a few more but that's off the top of my head.
Old fashioned churches like your MIL's are loved by many (often elderly) but there are lots of different more modern churches too.

A congregation of 400 at a time? 3 services a day, (the vicar must be run off his feet!) acting, dancing, live bands playing, mother and baby groups, food bank, night shelter, lonely peoples lunches, street pastors, counselling, debt counselling, tradecraft markets, a work scheme for adults with learning difficulties, mens groups, womens groups, parenting course, marriage courses, (? 
) evening services, uni students flocking in.....Where on earth IS this amazing Church?
