This one’s noticeably superior to 'Hart to Hart Returns,' from my perspective anyway. It isn't particularly impressive overall, however. 'Hart to Hart: Home Is Where the Hart Is' presents a more compelling narrative and a pleasant environment compared to the previous movie. The storyline still follows predictable patterns, which impacted how much I liked it and prevented it from earning a better score, but there’s something extra about it at least. The actors are agreeable but not particularly memorable once again. Stefanie Powers is the strongest performer, while Robert Wagner seemed to have a less prominent role in this film—as did Lionel Stander. Wagner does appear, of course, but it felt more like a vehicle for Powers’ character. The other performers were acceptable; they're at least an upgrade from the last one. I am curious to see what the third movie will bring.
