No list of "5 worst of Star Trek" can exclusively diss the original series and not find a fault with ENT; the last show was canceled for a reason: it was bad out of the gate and nothing they did to 'improve' it ever succeeded.
ENT made me realize that "The Way to Eden" is actually not only NOT one of the worst 5 of the franchise, it is frankly better written than ANY episode of ENT; sure, it LOOKS silly, but it is technically far superior to the poorly-plotted stories of ENT that haven't even a grasp of BASIC science, let alone any of the pseudoscience common to Trek and most other sci-fi (remember when they plugged a hole in a leaking spacecraft hull with MASHED POTATOES?

)
You also completely ignored "Threshold" from "Voyager"
