The Wish has gotten a lot of critical reviews from
DCL regulars (poor layout, some poorly executed spaces, crowding, etc.), so I wouldn't prejudge DCL's entire fleet based on sailing her. The other four ships currently in service are quite different from the Wish. If you ever give DCL another chance, sail one of the original four.
Other than that, yeah, cruising might not be for you if this was your first cruise and you hated it. Cruise food is generally not as good as food on equivalent land restaurants, because it's mass produced and complimentary. That is a mass market cruising industry standard. I've found that it helps to listen to server suggestions on what to order from the MDR dinner menus. The upcharge adult restaurants have the best food by far.
But keep in mind that some planning does make the experience smoother, just like at WDW. For example, it's better to pack your suitcases & put them out during a lull midday, rather than rushing back to the stateroom to do it during a busy evening. (You can put your final evening's clothes in a carry-on bag.) Things like that can make the experience better.
So can cruising for 7 nights rather than 4 nights, so the pace is more relaxed. 7 nights is a pretty standard cruise length. 4 nights is a short, quick cruise, and is more prone to making new cruisers in particular feel rushed.
