Grew up in the time of Knight Rider. Tried to watch it not long ago, wow. I couldn't, LOL. Same with The A-Team. Tried to watch it a few years ago, couldn't.
Also 21 Jump Street. Also tried to watch this just a few months ago when I found it streaming. I am floored that Johnny Depp could expand beyond that. Then again, I've seen his later movies, his acting just as horrible in his movies as he was in 21 Jump Street.
