“Batman: Gotham By Gaslight” (**1/2 out of four) was a generally entertaining animated action drama set in an alternative Victorian Age Gotham City in which Batman (voiced by Bruce Greenwood) investigates a series of murders by none other than Jack The Ripper and realizes only he can stop him. Undeniably silly and murky in setting the Batman story in a different time and century but is fast-moving and features some striking and colorful animation that makes it soar. Worthwhile for Batman completists and animation fans.
