I find it strange that your opinion if the 3rd is "but no soul or emotion.". May I suggest that you look for a different performance and/or have soe more listens?

Pay attention to the developmnt and dialogue of the instruments. The mood changes are not "just there". They too carry meanings, and should in no way be percieved as "show off".

May I remind you that the subject is heroism. It is inspired by the french revolution. it carries the spirit of conflict, the death of a hero, freedom and new ideas. You cannot just state "it has no passion", especially with just one listen.

You can just see the revolution in beethovens thought through those little "quirks" here and there, unusual for the era rythms, the hard hitting "fanfares" of the strings, the lack of a steady, monotonous mood, all these are a revolution in their own way!

I like Karajan's performances but I suppose you can find much higher quality recordings in terms of sound and recording technology.
