Ident Tropes

[Blubatt]

What are some common features of Idents you love or hate? The Youtuber Matthew Harris has been clear in the past that he finds live action idents, with a logo stamped on top to be weaker than those that have a solid, single symbol. I want to know what the rest of TVLF think on the matter? For me, one thing I really don't like in idents is a tendency to reduce the length of an ident over time, for the continuity. I understand why its done on channels like ITV or Channel 4, but BBC and its circles were horribly cut down, which made the ident less fun, and gave us less of what I consider to be a good form up.
