Three strikes...
Three things that really annoyed me about Gidget.
1. The laugh track in the pilot episode. Never before was it so obviously added at the last minute. What's really annoying is that a show like Gidget, which is more reliant on wit instead of gut-laughs, really shouldn't have had a laugh track at all.
2. The title sequence is almost embarassingly lame.
3. Gidget suddenly has two different bedrooms. (and this isn't even a pilot/rest of series change either)
Of course, add the great writing, decent acting and pathecolor, and you have something legendary. I still can't believe how much they were able to get away with in 1965 (the first episode was all about sex, after all, and Gidget makes some comments at the end about her brother-in-law being sexually frustrated)
