I think it was a great ending. A lot of shows try to carry it on longer that it's mean to go, to only see the show get worse and lose steam (maybe just get cancelled).
They planned 5 seasons, and stuck to it. Plus, the finale was done well. We've watched a lot of series finales, and I think a good a mount of them just miss entirely.
Currently looking for the following comic Books:
United Comics: 21,22,23,24,26
Tip Top: 173 & 184
Peanuts 1 (1953)
Peanuts: 1-4 (1963-64)
