The early 1990s were a very different time for television. There was no CW or ABC Family, so tween girls were forced to look to family sitcoms for their celebrity crushes. Home Improvement’s Jonathan Taylor Thomas graced the cover of many issues of Bop magazine. (There were no blogs back then!) Now he is all grown up and reuniting with his Home Improvement Dad Tim Allen on the season finale of Last Man Standing. His appearance has been heavily promoted. Will his former fans, now part of the 18-49 demographic, tune in for a dose of 1990s nostalgia and help the show wrap its season on a high note? Last week’s episode garnered a 1.4 adults 18-49 rating. How will tonight’s fare?
