Švejk is too much slanted by the expectations of “just funny” and by (absolutely awesome, but too nice) illustrations by Josef Lada. When listening to the audio version of the book, I was shocked how actually horrific story it is. I have mentioned elsewhere in this thread a Czech literary historian (M. C. Putna) who called “The Good Solider Švejk” as “Kafka’s ‘Trial’ by other means”. I think he is quite correct.
"Heller, who died in 1999, told various interviewers that Céline and Kafka were his most powerful influences and that "Svejk" was "just a funny book.""
"The Czech writer Arnošt Lustig claimed that Heller had told him at a New York party for Milos Forman in the late 1960s that he couldn’t have written Catch-22 without first reading Jaroslav Hašek’s unfinished World War I satire, The Good Soldier Schweik. "
I was really surprised by Closing Time. I forget all the details of it, but I remember finding it just relentlessly depressing. The only degree to which I thought it worked was, it really emphasized the extent to which we really don’t need to know what happens to characters after the story is done, it is better if we just imagine they go on to have their lives.
I thought Svejk was more available to a younger reader. However, like someone already mentioned, it has enough layers for a reader of almost any age to enjoy. I'd read them both.
I think if you like one, you like the other. I think the Svejk book have a more innocent tone and is less cynical. But I was way to young when I read them to have a "deep" understanding of the contexts.
