"Excelsis Dei" is a better-than-average episode that could have easily been a season two gem if not for a muddling storyline. Dana Scully finds the case, creepy settings are abound, ghosts and invisible rapists are on the loose, and the script is rounded out by an excellent guest cast. Unfortunately, Paul Brown's story is a little too ambitious for these high spots to beggar the myriad plot strands that undermine them.
It doesn't help that this comes on the heels of a particularly confusing mythology episode. Like "Red Museum" before it, "Excelsis Dei" dabbles in a lot of unsettling social themes: rape, abuse of the elderly, abuse of women, the encroachment of immigrant cultures - and twists them into a bizarre knot of conjunction and happenstance. A nurse at the Excelsis Dei convalescent home (Teryl Rothery) is strapped to a bed and violated by an unseen presence. A male Asian nurse (Sab Shimono) dispenses presumably illicit pills to residents that have invigorating effects. A creepy mushroom garden is found in the facility's basement. An elderly woman wheels the corridors conversing with ghosts. But where does it all come together? As one might imagine, this episode makes for some great imagery. The drab grays and greens of the building's snaking corridors lends to the eerie quality of the script. The scene where Mulder and Nurse Charters hall-surf out of a flooded bathroom is particularly delightful. Also, Gillian Anderson has some great lines of dry humor. Although there aren't a whole lot of intimate character moments between the two agents, their chemistry continues to shine.
Unfortunately this episode leaves the viewer with too many questions and too few answers. We don't know whether or not Hal Arden traveled out of his corporeal boundaries to rape Nurse Charters. We don't know how the magic mushrooms evoke the presence of spirits (or are they simply hallucinations?). Where is Leo dragged off to in act four? Ambiguity can and has worked in plenty of episodes of The X-Files, but it's hard to excuse a script that fails to offer answers to any of its questions. Still, "Excelsis Dei" is creepy and enjoyable. 6 of 10.
