Enterprise was just stupid...
Enterprise followed the same "first two seasons suck" rule that TNG, DS9, and Voyager did. Season three, and
especially season four, were quite good.
To be honest, I think Enterprise is a better show than Voyager - at least Enterprise actually embraced it's prequel premise and had some serialization, vs. Voyager which was a TNG-retread with few consequences explored of being trapped 70,000 light-years from home. If it had gotten seven years instead of four, and kept building on the momentium it had in late season three and most of season four, it would be on the same quality playing field as TNG and DS9.
