I recently got the first 3 seasons on DVD. It's great that you can turn off the laugh track... and finally see some missing scenes. I wish the DVD had a Play All feature though. Anyway, great show... my favorite sitcom ever. Since i grew up on it, 4077 feels like home to me.
Just saw Blake's death last night ):
I won't watch anything past season 3 though. I used to, but the dynamics of the camp changed in unfunny ways once Blake left; no more ineffectual leader with the corporal who is really running things. I never liked BJ. And all the characters became slightly watered down versions of Hawkeye... even Houlihan eventually.
