PROBLEM: Review: Recently I ordered 'Stopped at Stalingrad' from amazon.com. It was well worth the puchase, as the book is both a profoundly researched study and an interesting read. It's a scholarly work which, undoubtedly, will become a classic in its field.Dénes Bernád, Aviation Historian and Author

PROBLEM: Review: A Charlie Brown Christmas is my personal favorite Christmas movie for children of all time. The movie is entertaining and funny, just as the peanuts movies always are. Mostly, though, I love the fact that this movie pulls no punches when dealing with the over commercialization of a sacred holiday. Indeed, the movie comes together with Linus quoting from sacred scripture after Charlie Brown asks in frustration what the true meaning of Christmas really is.If you are parent who wants an entertaining Christmas movie for your kids that doesn't attempt to gloss over the true meaning of Christmas by using gushy messages about peace on earth and family togetherness, but gets right to the point of Christ's birth, consider a Charlie Brown Christmas. You won't be disappointed.

PROBLEM: Review: The book was wriiten very horribly. I would never in my life recommend such a book. The stories lacked any mystery to them and did not leave me wanting to figure out who the culprit was. The only good thing was that none of the stories took up ten or twelve pages.
