I feel very similar, now i keep hearing how this show is the best thing since the invention of bread.

Its good. Its another one of those good HBO shows.
Its not mind blowing. The only tv show I would highly recommend to watch is 'the wire', it is amazing.

+ some BBC nature documentaries

The name works, somehow.
Also, note that this whole scene is one long, amazing, tracking shot.

Spoiler: one of Marty's daughters is an Encyclopedia Brown-like genius, and in later episodes she's the one who blows the case wide open. And her name is Trudy ... Trudy Tective.

Yes.

exactly, essentially all three, and they're fucking SCHNOTTERED on speedballs and meth

better?

Well, I know you're going for linked tags. The previous poetv users were wrong as to the definitions.
Short answer: it's a long take because of length of time, and a sequence shot because of 'choreography'.

Most of the definitions are not debatable ('tracking shot' is).

To me and my books:

Tracking shot = the dolly is up on tracks and moving the camera during the take. Can be a long take and often is.
(some people will call a tracking shot the act of 'tracking one subject over a long period'. I think this is not the original definition.)
(some people will call a tracking shot a long take, since they overlap a lot. I think this is probably just pure denotational drift.)

Sequence shot = a long take + multiple camera movements [whether on track or off or handheld] + usually complex blocking/movement of actors or objects or both.
The definition gets fuzzy with fewer, simpler camera movements, and fewer simpler subject or object movements.
So this type of shot is done often, but the term is not used as often as it could be.

Single take = one take from from rolling to cutting, as opposed to multiple takes [as in, just one piece of footage, irrespective of whether the camera set-up is the same]. Can be long or short.
(some people will confuse this with a long take, probably because of conflating these two terms: 'long take' and 'single shot cinematography' which mean the same thing.)

Long take = a take done over a long time, with the intention of covering action for a long time. Sometimes entire scenes will be covered with a long take, which leads us to a

Oner [the # 1 plus suffix -er] = denotationally synonymous with a long take, but I believe that the connotation is often that the whole scene is shot with one long take.

Long shot = opposite extreme from close-up

single (shot) = a shot with only one subject, usually named by whether it's a close-up or a medium shot. The definition gets fuzzy when it's a long shot but with only one person in it. To me it's still obviously a single shot. Not to be confused with 'single shot cinematography' which is getting through a scene with only one shot, as opposed to covering the scene with two or more different shots.

so, long take?

yeah!
i'd guess we don't have sequence shot linked
