Who loves the prolonged American intros?

Yeah-They're awful, and interestingly, noticeably done at a different time (and different budget) than the original British intros and episodes. It's actually how I first saw these in the early 1980's running on late-night TV during the weekdays on an independent NY TV station at about 2 in the morning.
Actually the original episodes ran about 65 minutes. This was too short to run in an allotted standard 90-minute time slot (with commercials) at the time. At that point on American TV 90 minute shows on commercial stations actually ran about 70 minutes, with 20 minutes of commercials. So us "classy" Americans simply excised the British opening/closing credits and added about 5 minutes to them, which is why they run so incredibly long. Nowadays, oddly a 90 minute time slot on commercial TV would have about 25 minutes of ads, so these would/could actually be shown as originally intended.
The ONE thing I liked about many of the American credits though were the very early-70's look they had to them and the fact that some of the artwork featured in the closing credits (which often depicted characters from that particular episode) were actually paintings done by some talented artists. But that's about the only benefit to the American credits.
Still it's a blast to actually see them tagged onto the end of the episodes on my British PAL DVD set.
