Stick with it, trust me and this board.
B5, for all its faults and substandard acting and stand alone episdes, spins a great tale that unfolds bit by bit until it is completely revealed and the excrement has hit the fan
The first season, while overal not the cream and brilliance of SF TV, is still very important in setting up the universe, characters (though some characters change tremendously and for the better, G'Kar for example) and overarching plotline has rarely been seen since.
While Star Trek shows boast better sets and effects and overall had better actors B5 still has the most epic story that TNG never was able to reach (DS9 was awesome once the Dominion was introduced but it pales to the epic story of B5).
The effects are of course outdated since it was a 90s show on a TV budget but it's still watchable so as i said.. stick with it, season 2 kicks ít a gear higher and season 3 is all around pure brilliance and gripping from start to finish.
Due to TV production realities, the producer and boss of the show JM Straczynski was unsure if he would get the promised 5 seasons and so had to adapt season 4 to conclude the main storyline which may have felt a bit cramped but at the last second he got season 5 but then it was too late to follow the original 5 season storyplan so he had to extend th show and find new storylines which were not bad and set up a wider universe for the spin off shows which sadly didn't do so well and were cancelled.
So enjoy the ride, it is one of the best epic SF shows ever produced and shows what can happen if you have a really cool story to tell and plan it through from the start. You'll enjoy the show again once you have seen it completely and how subtle sometimes the hints were at things to come but they are there
