4. Guest Stars and Tribute Episodes
Lumped into a single category partly because they sometimes coincide but mostly because they both always distract from the focus weve already seen haphazardly spread away from the characters of Glee that fans love. Since Season one I cannot recall a guest star really advancing the plot perhaps the closest has been Gwyneth Paltrows Holly Holliday in bringing Will and Emma finally together after a courtship so drawn out the majority of viewers were bored by them. Ricky Martin, although fantastic in his role, was used to demonstrate that suddenly Will a previously competent Spanish teacher was useless at his job and could barely remember simple grammar. Likewise, tribute episodes can go either way but mostly seem to head in the direction of an overuse of songs taking up screen time that would be better suited for narrative.
