Hi, first post here!
Dream, if you like shows like 24 and Lost, you'll like PB. It's not that it's like these two shows at all, but it's edge-of-your-seat excitement with a weekly cliffhanger and a whole bunch of mystery thrown in every week.
Although I tend to agree with many of the comments here regarding the show's decline over the four seasons, I think it's a bit of a short-sighted critical analysis of the show as a whole.
The entire four-season run is pretty good overall. If I were to review it today on my blog I'd give the series a solid 7 out of 10. What hurt it was its first season which was so good it simply didn't leave the writers with anywhere to go so for the following three it became a little contrived and very convoluted revolving around government conspiracies and frankly, some really unbelieveable premises. Without a doubt, season one was a 9 to 9.5.
Now is this to say that the show was awful for seasons two through four? No, not at all. Despite all of its flaws, confusion and general eye-rolling silliness, the show was very effective for four seasons for two reasons.
First, it did exactly what it was intended to do and that was keep you guessing every week with new mysteries, frenetic action and compelling mysteries and suspense. Second, and this is the most important aspect ot this or any show, the characters were richly developed and wonderfully casted... all of them.
That being said, I think the problem that most fans had with the show is that it never approached the level of quality that season one was known for. Often we confuse that for being bad. It was never bad, it just never was as good as that first season.
When you're done watching the series, I would highly reccomend the direct-to-video 90 minute movie/episode, Prison Break: The Final Break. As a new PB adventure, it's OK in and of itself, but what's important about it is that it ties up a lot of loose-ends and gives the series as a whole a sense of closure that was absent in the series finale.
