Yeah the first episode is just a intro to the characters to the show Shyguy. I actually got hooked on the show on the 7th episode. Dragonshy.
Paleosteno did a Season 1 video review of all the episodes.
Also fun fact about season 1. There was actually censors on season 1 so they couldn't take it as far as they could in season 2. You may have seen some EI on some of the videos.Although I am kinda surprised what they got past in season 1.
For best of season 1 I would recommend these. Dragonshy, Look Before you Sleep, Swarm of the Century,Winter Wrap up, Suited for Success, Sonic Rainboom, Green isn't your Color, The Cutie Mark Chronicles, Party of One and The Best Night Ever.
Just below that I would put Boast Busters, Bridle Gossip, Fall Weather Friends, Feeling Pinkie Keen, Stare Master, The Dog and Pony Show,Over a Barrel, and A Bird and a Hoof.
For the rest of the episodes here. The Openers, Ticket Master,Applebuck Season, Griffon The Brush off, Call of the Cutie, The Show Stoppers, Owls Well That Ends Well.
While I have placed these ones down here I do still like them and they do have a piece of the show that I like or a character that I dislike and it does add character to the characters in some of the episodes.
There is really only 2 episodes I don't like to much in season 1. Griffon the Brush off and Owls Well and Ends well. The rest are great.
