Season 8 of Three's Company really was hit or miss in terms of quality. Plotlines tended to be reused from earlier seasons, acting comes off dry or stiff in some cases, or genuinely the conflict at play just wasn't interesting. 'Alias Jack Tripper' is one of the exceptions. It is one of the best episodes of the Terri era of Three's Company and features a great guest starring role from Rita Wilson. Really superb. Feels like everyone involved in this episode really put their heart and soul into their performance.
