 Erich <unk> of TV Verdict thought the puzzle @-@ solving storyline was " a lot of fun " , both for its references to the " highly entertaining " documentary Wordplay and the jokes it inspired . He thought the one problem with the final part of the storyline was that it took away from what could have been " one of the best Lisa @-@ centric episodes in a long time . Marrying her bookish sensibilities with <unk> skills is an inspired idea . They should have done more with it . At the very least , it would have left more screentime for Will Shortz and Merl Reagle . "
