I saw Oh, Heavenly Dog! At the movies when I was 14 years old in 1980 when it was a new theatrical release. I remember everyone of all different ages in the theater seemed to really like and enjoy it. I just bought the DVD for Christmas for my adult son and me to watch. We really enjoyed it, and will watch it again soon to watch the background scene activity. I enjoyed it even more almost 44 years later. It's charming and funny and Benji is adorable and Chevy Chase is likable and pairs well with the wonderful Jane Seymour. The story is actually not bad at all, and it should've been a way bigger box-office hit. Do NOT listen to snobby film critics-this gem of a film is a genuine winner. It's perfect to just chill out and eat popcorn. I wish more movies like this one were made today. I also enjoyed watching this movie for the nostalgia-It's practically a period piece now, with rotary telephones and non-high tech kitchen appliances, furniture, and late 70s-1980 wardrobe and fashions. Some of the jokes are corny, but SOooo much fun. Treat yourself and find this movie streaming or on DVD. It's definitely worth a watch. 8/10.
