I've used both. Queen's is a workbook, Serl's is not. Serl's is older, but still good, and its not archaic. I wouldn't say either one is overtly Christian. Although I've only used Queen's in the early elementary, not the older ones.
The advice I can give is we have been using Math U See for 7 years and love it. I'm using it with three boys and its hands on math. We really like it and will continue to use it through high school.
We saw it and loved it. We took our oldest three, 12, 10 & 8. Its a clean movie with a great message. The adult theme regarding "porn" stuff went over 10 & 8 year olds head and it was spoke about in such a way that it kept the movie clean for kids. They did a great job of keeping the movie family friendly.
Mice traps with peanut butter. Thats what works with us. Once we had a family of them in our basement. It took a few days, but got them all with peanut butter in a mouse trap.
Focus on the Family Plugged-In gave Fireproof a 5 out of 5 rating for family friendly. Heres the review http://www.pluggedinonline.com/movies/movies/a0004166.cfm
Did you see Facing the Giants? The acting in there was great considering they had a shoestring budget. I don't think the acting will be bad, if its like Facing the Giants.
