Cool Cat (1967 short)

Cool Cat is a 1967 Looney Tunes short directed by Alex Lovy. It was the first short starring its title character, Cool Cat, and his rival, Colonel Rimfire. It was also the first Looney Tunes short released with the Warner Bros.-Seven Arts title card.

Why It's not cool?
The cartoon's storyline is basically just your standard "animal vs. hunter" storyline that had been done dozens of times in Looney Tunes and Merrie Melodies shorts by this point.

Cool Cat barely even does anything in his own debut short, which focuses more on Colonel Rimfire, suggesting that they didn't really have an idea what to do with the character. This would continue throughout his shorts, with only his second-to-last one, "Bugged by a Bee", putting him in the kind of situation you'd expect to find a beatnik (namely attending college).

Colonel Rimfire is basically just a knock-off of Elmer Fudd, except with a British accent and somehow even more incompetent.

Speaking of which, Cool Cat himself is a basically just a knock-off of DePatie-Freleng's Pink Panther, Hanna-Barbera's Snagglepuss and Looney Tunes' own Bugs Bunny, but minus the humor and charm of all three characters.

It has an obnoxious use of Hanna-Barbera sound effects. Some of the sound effects choices are really weird as well, such as the chattering of Colonel Rimfire's dentures, which has the sounds of a tiki drum playing over it.

The ending is way too predictable, with it turning out that Cool Cat knew all along that Ella was a mechanical elephant.
