These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ass Pull: After spending most of Season 2 struggling to find opportunities for Lisa Gay Hamilton to stretch her acting muscles not portraying a lawyer, it is revealed at the beginning of Season 3 that Rebecca has passed the bar. She'd been taking night school classes, totally in secret... for the past five years.
Base Breaker: Some fans loved Alan Shore and his amoral antics, others thought he was a slimy Smug Snake and wanted him to go away
Deader Than Disco: The legal drama equivalent of NYPD Blue. At its height it was a smartly written, well-acted show with tons of Emmy nominations and wins; now it's barely remembered as a footnote in James Spader's career.
Much like NYPD Blue, this may be due to the show's lack of coverage on Home Media more than anything else.
Ensemble Darkhorse: Ellenor, in part for being a well-written overweight, female character on primetime television (something quite rare, unfortunately). The role earned actress Camryn Manheim both an Emmy and a Golden Globe.
Alan Shore. James Spader was a shot in the arm for the series and the role earned him an Emmy, as well as a starring role in a very successful spin-off.
Hilarious in Hindsight: In an intentionally botched closing, Jimmy questions why so many celebrities show their support for AIDS sufferers by wearing red ribbons, and asks why there is no ribbon for heart disease, which his father died of. Well, now there is a ribbon for heart disease... and it's red.
Jerkass Woobie: Alan looks just so HURT as Ellenor testifies against him in "The Case Against Alan Shore". Even though we're supposed to take from it that she's right, and he knows she's right...still, the truth hurts.
Narm: When Bobby realises that Barry Wall (Christian Clemenson, better known for playing Jerry 'Hands' Espenson on Boston Legal) shot Jimmy, they fight and break a window, and then Bobby hangs him out the window until he confesses to shooting Jimmy. The way Bobby says 'Tell me you shot Jimmy, or you are out the window!' comes off more funny than serious.
Nightmare Fuel: Before Michael Emerson played Ben Linus, played a serial killer on this show. In fact, The Practice probably has a lot more to do with the fact that he's typecast as a villain than anything else he's ever done.
Tear Jerker: The. Look. On Alan's face. As Ellenor is on the stand testifying against him, and says he'll destroy himself one day, she can't have that at her firm, etc. Try not to cry as you watch it, and ZOMG James Spader is such an awesome actor, even when he has no lines at at all.
