If you want you could. But you would miss out from some good episodes like: The Emissary, Duet, In the Hands of the Prophets, The Maquis, The Wire, The Jem'Hadar and about half a dozen others.
Though the first two seasons of DS9 are a little shaky in direction, the third season brings in the Dominion, and if you like that, then you will get the DS9 bug. Still watch the two seasons, only ten percent of the episodes are really
bad in those two seasons.
