Eran Stern posted a nice balanced review of Adobe After Effects CS5: Learn by Video:
"In summary, this comprehensive and interesting title includes dozens of hours of hands-on exercises. It is served in a nice, pleasant and professional way and gives emphasis on the important parties of the software. After Effects has grown and expanded so much over the years, that even a comprehensive product like this finds it difficult to cover all aspects of it. It’s apparent that the authors have gone into great detail and attention and I think anyone who devotes time to watch all classes will get most of the information he or she needs to start creating motion graphics with the software and perhaps even fall in love with After Effects thanks to the passion of the lecturers."
