This was, and will always be, one of the best original series that ever aired on TV. It came from future and of course, it confused many people. But to sit and really watch it, you can appreacite the work put into it.
The first season was the all time best season it could ever been. The scripts were well written and the acting was the best. By the second season, many people started to drifed from it. I guess the crew was half there and really wanted the old crew. This season as someelse said here was really comical but the plots got to be werid. A underwater adventure turned to a space adventure. The ending of season two was great but it brought out season three. Season three was the point where everything changed. The series tried to get back on track, for what seaQuest was all about- the sea. Like i said they tried. The characters changed overnight and the followers of the second season started to drift from the new cast. Some of the old favorites where still there but they have changed too fast. The character, Lucas, was one of the favorites that kind of kept the series togethor. But by season three, he was not a hyper teen we loved, he changed to a serious moody adult. And the change of captins did not help eihter.
I am not bagging on this series, it is one of my favorites but the writters could have done a better job.
