Here's my definite "The worst of Star Trek: ENTERPRISE" list:
15. E2 - a blatant "Children of Time" rip off with annoying guest characters
14. Marauders - boring
13. The Seventh - T'Pol character assassination
12. Precious Cargo - the whole 'T'Pol acting as a judicial administrator' nonsense was ridiculous (on the positive note - Trip got laid)
11. Fortunate Son - snoozfest
10. Bounty - its Pon farr time, everybody! *facepalm*
9. Horizon - painfully boring
8. Exile - redundant, uninteresting and seriously lame
7. Bound - silly, goofy and in general - unnecessary
6. Rogue Planet - BS galore
5. Extinction - seriously, that one was embarrassing
4. Daedalus - terribly boring
3. Dear Doctor - Phlox character assassination
2. A Night in Sickbay - Archer character assassination
1. Terra Nova - no plot whatsoever, annoying guest characters
***
0. These Are the Voyages... - A bad prequel to "The Good That Men Do"
*(the book would have been much better had this been a serious episode)
**(made poor St. Valentine turn in his grave)
