Taste being a personal thing, this question is about your deciding something just isn’t for you rather than slagging off others’ faves as being of little or no artistic merit (aka a load of old bollocks as it’s known in the trade). One man’s meat and all that…
Reason why the question came to me was the recent Crowded House thread when I thought that as I’d always been quite fond of Split Enz, I’d never really got deeper into the Finn’s more recent band than the better known songs (Weather, Dream, Cake, etc).
Subsequently bought the 2 CD Gold collection and got six songs in before deciding that myself and messers Finn et al weren’t – and were never likely to become – BFFs.
If I don’t really enjoy a book, I’ll generally chuck it within the first 50-pages.
While TV series rarely last more than one or two episodes, I did make a notable exception in the form of Peaky Blinders which I got four episodes into twice before deciding it wasn’t for me. Some stuff I just know I’m not going to like so don’t even bother to start (those US sitcoms where they have about 100 writers pounding out wall-to-wall gags.
Films tend to vary depending on who’s directed., written or starred in it. Unless it’s by someone like David Lean, anything over three hours tends to get a very wide berth or, like Scorsese’s bloated Irishman, viewed in episodic chunks.
