Original concept, but unfortunately still too many weak points

As in several bookstores in addition to the Harry Potter books, I have the Lemony Snicket books-see stand, at first I thought the books were a Harry Potter rip-off. The is fortunately not so! The story of the Baudelaire children has hardly similar to the Harry Potters. The fictional author Lemony Snicket, tells the story of three orphans and plays again and again in his own mysterious story, which he revealed to the reader from book to book fragmentary. If one opts for the first volume, you should expect that you will then read all the other books, because the books always have an open end.
The first volume of the successful series introduces the characters. The tech-savvy Violet, Klaus and the readers worth the small Sunny lose their parents in a fire and are now looking for a new home. Since it is the portrayal of unfortunate events, the original title of the series promises to the disaster is already pre-programmed course.
However, I have (too) often wondered why so intelligent children as Violet, Klaus and Sunny make repeatedly rather silly mistakes, such that the villain Klaus reveals his plan. The basic concept of the series, although the description of unfortunate events, but the protagonists were supposed to act a little smarter, as the unfortunate events caused mostly by Violet, Klaus and Sunny even. This is actually the point that bothers me about the books most: the preventable errors, together with the clear indications about the author. Few surprises should be the reader finally granted. JK Rowling has the 'Foreshadowing' mood much better. In addition, the repeated definitions of the author are in the first book still quite annoying when helpful for the foreign reader. The author creates ultimately though, to move the reader to buy the next volume, but only because the reader wants to know what happens next, and not because the stories would be so awesome.
