Yes that is the correct category as that is what both are predominantly .As someone else has said they do veer into sci fi territory for some episodes but in general crime is more accurate
Weren't there US releases for:
Man In A Suitcase
Jason King
The Secret Service
Jonathan Creek
Midsomer Murders
Foyles War
Inspector Morse
Lewis
Broadchurch
Life On Mars
I'm sure there are many many more
Neither of The Avengers shows can be classified as sci-fi.
