Whilst I respect Haddock's views I feel he is approaching this from the wrong perspective.
If you like Tintin , and I'm a Tintinophile myself, then the only comparison is that Jacobs and Herge were Belgian and Jacobs worked improving the reprints of the books (see The Black Island - constumes and uniforms of police and Fire brigade plus other Sundry Angloscotish isms) Jacob's books are not about humour. Heck the setting is in the world of the 1950s and polictics. as for too much reading I had thought this was a graphic novel! A picture is worth a thousand words anyone. No I actually prefer Jacobs books and I feel whilst they may be enjoyed by the younger reader are aimed more at the mature reader (say 12+). It's a little like comparing the sublime Tintin's Blue Lotus to The Lake of Sharks.
