I'm not familiar with the book 'Dear Mama' (Dear Mom), so I can't compare. This 6 part mini series is watchable, but barely. You'll have to ignore a lot of illogical, or downright stupid choices by the main characters, and twice as much improbable conversations and situations. Acting is flat. Plot is very predictable. Rifka Lodeizen can do a lot better than this. Due to the tottering scrip she obviously couldn't make much of her role.
