Classic Who went through enough changes that there might be something you enjoy in there. It was arguably at its best during the Tom Baker years. (Season 12). If you can't get into that, then it may just not be your jam. A lot of the charm to the old series came from the low budgets and aggressively short production times. But with the 4th Doctor they had gotten a little more confidence from BBC and I think their budgets started getting bigger for a few years.

The original Doctor Who in the 60s was more like original series Star Trek, in that it sometimes felt more like a stage production than a television show, and that kind of writing is understandably dated.
