Virtually every book, TV show, movie, and manga uses at least some of those without being considered classics. Using mythology and involving real world themes is also pretty common and can be found in plenty of kids books too. Also, using Deus ex Machina isn't a good thing and frequently (although not always) is a sign of lazy writing.
