The Blackmar Diemer has many views and opinons based on different people.
On the Blackside some laugh so hard that White utterly begins to freak out. While on the Whiteside it turns into somewhat like a boxing match.
IM Andrew Martin says "the infamous and rather generous Blackmar-Diemer Gambit. I must say that I am delighted to see these moves as black because I understand my opening choice was successful."
As well as IM making this opening a laugh stock. It only seems to get worse with the variation names. For example the Hara-Kiri Gambit line which in Japan would be translated at the Suicide Gambit which we will leave it at that.
Nether the less I still have chosen to adopt this opening (even though I lose more often ) due to the games exciting nature.
