The happy-go-lucky, flashy tone of the course is completely misleading. It is a challenging course, so much so that it’s been the subject of numerous cheating scandals from students caving under the pressure over the years.
As for depth, this is a first intro to CS meant not only for CS majors but for people from other domains (Econ, humanities, hard sciences, what have you). The style is meant to cater to people who might not be a priori fascinated by flipping bits. Still quite a bit of people decide to concentrate on CS after taking the class, so it must be doing something right in that sense...
The course is not mandatory for CS concentrators, so if you already know your fundamentals you can jump right into CS51 (functional programming) or CS61 (intro to systems), which are outstanding courses but much more terse in style.
