TAMPA The best open house this holiday season runs this week, but itís not about nostalgia or sentiment. Fun Home tells a true story of the cartoonist Alison Bechdelís upbringing in a lovingly dysfunctional family. The graphic novel of the same name she created is densely packed with congruent thought and imagery, at once meticulous and joyously messy. Competing themes include the jarring ways in which all families operate, with the capacity for deeply moving affection and random cruelties by the same people; the nadir of internalized shame and the end result, which just happens to parallel the family-run funeral home business.Itís only natural that something so fresh and boundary breaking would be made into a musical. The question is, would that form help or hurt an already rich artistic product in the book? Local audiences also no doubt hope the touring show will reflect the glory of the Broadway production.The answer here is a qualified yes and yes. This story exudes originality, portraying complicated topics with childlike simplicity ó well, also adolescent anger and an adultís hard-earned insight ó only now with a musical dimension. Qualified, because the form that packages that added dimension smacks of the mechanization of musical theater. In fairness, those features only stand out because Bechdel by her own account didnít draw her memoir with any formula in mind, a stubbornly independent trait that factors strongly into the character.Nonetheless, these manipulations work often enough to create a stirring, thought-provoking piece of work. Alisonís father, Bruce (played with versatility and care by Robert Petkoff) is an English teacher and part-time funeral home operator who lives a double life under everyoneís nose. His three children absorb all that they can see, while Helen (in a finely drawn portrait of quiet suffering by Susan Moniz) sees her husbandís serial philandering with men all too clearly.Alison is played by three actors. Small Alison (a terrific Carly Gold) receives love and genuine nurturing from the same man who verbally abuses and disrespects his wife. Medium Alison (my favorite of the three, the golden-voiced Abby Corrigan) comes to terms with her sexual identity without even suspecting her fatherís, cemented in a thoroughly wholesome scene with Victoria Janicki, who as Joan ushers her into her first sexual experience with a woman. The resulting song, Changing My Major, is a great example of everything that works about this musical.Examples of what falls short are a pedestrian suicide-by-truck that chickens out on the impact. There is a difference between sensitivity and timidity, and this is the latter. Then thereís the unresolved problem of how to stage the ever-present adult Alison, a future-self-looking-back played by Kate Shindle, who seems more to be imitating Bechdel than acting the role. Nonetheless, she nails a pivotal song (Telephone Wires) and does as best as anyone can at remaining unobtrusive on stage amidst a swirl of relevant action.Compared with the soaring beauty of so much of what unfolds, such quibbles donít really amount to much.
