Sometimes, I really like Seminars/Training like these, so long as I am not asked to participate. Ha ha ha ha.
But in reality, these are usually a very good exercise to get to know your colleagues better and also, form a closer bond, which usually lasts for weeks. That is, if the seminar was good. When I was with my first job, these seminars are very effective and well, the result speak for themselves. They used emotions and also, force teamwork on you.
Sadly, as a Banana, I could only understand 5%....sigh. Luckily, I more or less know what's its all about as I have experienced it before. How I wished I could go 100% instead.
