When 'Lost' was in its prime, it was must-watch television. Remember first watching it, found it remarkably easy to get into, was hooked from the start and was on Season 3 by the end of one week. The general consensus is that the final season is a disappointment and cannot disagree.
It, Season 6 that is, started promisingly enough with "LA X", both parts, before reaching disappointment with the still watchable "What Kate Does", which had great moments but a dull and soap-heavy central story. "The Substitute" is a step up and perhaps the best of the four episodes up to this point of the season, but not one of the best 'Lost' episodes. Did find a couple of issues with it but can understand why critically it has been positively received.
Lets start with the issues. There are no real answers provided here, there are explanations that easily could have been provided but don't come and felt overdue at this stage like with the Oceanic Flight 815.
Not all the character motivations are clear enough either, it can be frustrating when one doesn't understand some of why certain characters behave the way they do and what their goals here in a season where it's preferable to have loose ends tied up all the time. Maybe structurally it's occasionally slightly rushed as well.
However, "The Substitute" really excels in the characterisation, character work and character interaction, much of it evoking classic 'Lost'. It is a terrific showcase for one of the show's greatest characters in Locke, one of few to remain consistent and interesting in terms of writing and acting quality throughout. His story, both in flash-sideways and original timelines, here is not repetitive of what we already know about him and is compelling and emotional. Also was intrigued by the six numbers/names mystery and with Jacob, which did grab the attention and didn't confuse too much.
Cannot fault the acting, which is uniformly very good. Superb in the case of Terry O'Quinn. The visuals are stylish and atmospheric, while the music is understated and chilling and the writing taut. The directing has breathing space and alertness.
In conclusion, very interesting and well done episode. 8/10 Bethany Cox
