The FX may have been hard to look in the pliot... but in season 3 the nailed it... by then they hit full stride where massive armadas and big space battles were the norm. The work was so well done that Foundation Imaging who originally had a contract to produce visual FX for te life of the series was let go and Doug Netter had an in house team produce the FX using all the foundation imaging assets.
Foundation imaging later went on to create visual FX for tar Trek Voyager and Enterprise until they went out of business in 2002.
