My biggest beef with the show (besides the bad scripts and shoddy animation), is that in season 2, a bizillion characters show up with no explanation. Except for the Aerialbots, combaticons, and vehicons of course.
Season 1 we got:
Autobots: Optimus prime, wheel jack, Trail breaker, cliff jumper, prowl, blue streak, brawn, bumble bee, Jet fire, snarl, grimlock, slag, sludge, swoop, Iron hide, ratchet, Jazz, hound, huffer, gears, mirage, sunstreaker, and sideswipe
Decepticons: Megatron, Starcream, Skywarp, Thundercracker, Rumble, Frenzy, Ravage, Lazerbeak, Soundwave, Shockwave, Reflector 1, reflector 2, reflector 3, Bombshell, Kickback, shrapnel, Longhaul, Mixmaster, scavenger, bonecrusher, hook, scrapper, and Devastator if you want to count that.
Lets see in season 2 all of sudden these characters come along. Some introduced but mostly out of the void:
Autobots: Omega supreme, Perceptor, Tracks, Silverbolt, air raid, slingshot, skydive, fireflight, Smokecreen, blaster, red alert, inferno, grapple, hoist, beach comber, powerglide, cosmos, warpath, seaspray, steeljaw, ramhorn, eject, rewind, and maybe the protectobots
Decepticons: Astrotrain, blitzwing, Ramjet, Dirge, thrust, brawl, blastoff, swindle, vortex, onslaught, dead end, breakdown, motor master, wild rider, dragstrip
In anycase they could have had these charcters, the autobots anyway, appear via transport through omega supreme. Imean they just show up out of now where, What where they hangen out in the breakroom the whole time.
I realize its 30 minute toy commercial, and my comments also display how it was, but come on, that could have made a good story.
