Allright, I'll admit that the concept is a bit limited, but if you think about it, every show on television has one repeating theme. So if you can get past that, you'll find Seven Days to be one of the most entertaining shows to hit primetime TV in a long time. Johnathan LaPaglia plays Frank Parker, a former soldier who spent the latter part of his life in the looney bin, until the NSA recruited him for a top secret government project. They've developed a device that can take one man back in time 7 days. As you can probably guess, every week something horrible happens, and Frank must travel back in time to prevent it. What makes Seven Days so good is the characters and their interaction with each other. LaPaglia is very likeable, and plays the hero role very well. He's not perfect, but yet perfect for the job. Justina Vail plays Olga Vukavitch, a sexy russian scientist who quickly becomes the object of Frank's affection. Watching these two flirt back and forth makes us long for the day they actually hook it up and stop kidding themselves. Having that kind of sexual tension is good for any show. The rest of the cast is made up of folks you've seen in other shows and films. Although none of them are famous, they all play their parts with perfection. The plots, while repetitive, are always filled with action and suspense, and occasionally hints of romance. They do a great job of NOT limiting their audience to any particular group. The production values tend to run high in each episode, especially in the first season. I would advise anyone who would like to get into this series to look for the two-hour pilot to be re-run. It's always hard to jump into the middle of a sci-fi series storyline without knowing the facts leading into it. Many people have said that this show doesn't reach it's potential. Just remember, it's still relatively new to television, and like any show will take time to grow. X-Files didn't pick up it's popularity until the third season! I see quite a bit of promise here. After watching a couple of episodes back to back, you'll understand what I mean. If it doesn't last, look for LaPaglia to move on to bigger things. He could be the next Mel Gibson.
