Nothing is sacred anymore, but there really should be limits — even for Disney. "Alice Through the Looking Glass" is the sequel to Tim Burton's somewhat disastrous "Alice in Wonderland" (2010), which is where they really should have drawn the line. I regret to report that things in Wonderland have gotten considerably worse since Alice's last excursion down the rabbit hole. Lewis Carroll, who is credited here as one of the writers (the other is Disney's prolific in-house scribe Linda Woolverton), is likely turning over in his grave to look for a stiff drink.
