There are some good ISOTs, but I think the ASB subgenre that's universally bad is the Person ISOT, since they're all about removing the good bits of the ISOT genre (culture-shock interactions between the past and future) in favour of the bad bits (epic future guy pwns the past) with a side-helping of armchair general.
The only remotely good one I've seen was a Mazda mini-TL about a modern-day lad ending up in the body of an Ulster Unionist in the Sixties, and that was drawing much more from Life On Mars then the internet form of the genre.
