It should have been at least ten episodes. Hell 13 eps would have been ideal. One for each gym, one for the Rocket base/lavender town shenanigans, some for Sevii islands tomfoolery, culminating in the battle with Blue and then maybe catching Mewtwo.
The Lavender Town subplot here felt hamfisted and poorly executed, and completely ruined whatever sense of momentum the series would have had.
The shameless Megazard plug was awful, regardless of how cool the rest of the battle was. And also like what

>>16356696 said, the over reliance on Charizard was Ash tier retardation
